Applicationlune 27, 1949, Serial No. Long Oil, Penta Erithritol esterified Alkyd Resin modified with Soya Bean Oil. These improved alkyd resins dissolve in hydrocarbon solvents and form solutions of high viscosity, which dry at much faster rates than the comparable solutions of alkyd resins with oil lengths from about '70 to about 80% prepared from phthalic anhydride (or orthophthalic acid), pentaerythritol and a semi-drying oil. An alkyd resin, as defined in claim 1, wherein said phthalic acid is terephthalic acid and said semi-drying oil is soybean oil. The viscosity of its 60% solution in 350 mineral spirits is equal to about 0.2 poises at 25 C. Applies. Long Oil - Medium Oil - Short Oil Alkyd Resins Alkyd resins are produced by reacting a dibasic acid with a polyol and drying oil. Spontaneous emulsification of the ensuing hybrid resin … For this reason, only the chemical modification of … Solvent release is better in case of PTBBA and gives better solubility in xylene. The term alkyd resins as employed in this specification shalldesignate generically polymeric polyesters of polyhydric alcohols having more than two hydroxyl groups and resinifying olycarbokylic organic acids or their anhydrides. 0 The word oil as used here denotes oil obtained by esteriiication of a polyhydric alcohol with monocarboxylic fatty acids. ��w���*I$B��0�Q�$�����VCx���y��\G���jn�vW�: ���咰��X�N��0Kg�x� � ̛����z�kB��$Ǻ�����R�ǥ^z�.+�K�x�< ��8&�C�V�)��I"�A�Im������KM����H�u��,�����JMUY��S_]�N���h6e.�1-���v z!2T�wt��Vq������� �&E���Rw*�A�v�*� �4���\n��;��5�~W���u��k��ѯ�N��G�zu�'��l)��k��Я�N�C���Э�mi��b]{�uM�f]o7�Z�&?R� Alkyd resins are produced through the polycondensation of polyols, polybasic acids, monobasic acids and fatty acids. This may be effected by the direct one-stage cooking of monocarboxylic fatty acids with a polyhydric alcohol and a polycarboxylic acid in one single stage. My invention relates to oil-modified alkyd resins having a high content of semi-drying oil and a high viscosity in solution in a hydrocarbon solvent sufhcient to cause fast drying of such alkyd resins When employed in protective surfacecoa'tings. The resulting partial ester mixture is then heated with 0.68 mol of isophthalic acid at 245 C. for 2 hours to an acid number of 30. Castor oil is not commonly used in alkyd resin formulations and there are few reports on the alcoholysis of castor oil triglycerides. Epoxy resins are generally combined with curing agents, modifiers and other additives into formulated coatings, adhesives, compounds or mixtures which deliver the needed performance for a specific end use or application. An alkyd resin, as defined in claim 6, wherein said semi-drying oil fatty acids are soybean oil fatty acids and said phthalic acid is terephthalic acid. 1 hydroxyl groups per molecule, said alkyd resin having a semi-drying oil length of 70 to 80%, calculated as triglyceride, an acid number of less than 15 and being further characterized by its ability to dissolve in 350 mineral spirits to produce a 60% solution having a viscosity of at least 4 poises at 25 C. and a. tack-free drying time of about 2 hours.

The first stage consists of heating the oil containing monocarboxylic fatty acids in the form of triglycerides with a polyhydric alcohol, in order to produce a mixture of partial esters of polyhydric alcohols and monocarboxylic fatty acids by the so-called alcoholysis of the oil (described in U. S. Patent 2,044,747 to Ott, Bernard and Frick). at 260 C. for 3% hours until a resin having an acid number of 13 is produced. The: resulting mixture of partial esters is combined with 2.24 mols of a mixtur of isop-hthalic and terephthalic acids in a ratio of 3 parts of isophthalic to 1 part of terephthalic. Thanks in advance. If desired, a portion of pentaerythritol may be withheld from the reaction of formation of partial esters of pentaerythritol, as the presence of an excess may result in the occurrence of inter-reac tion of pentaerythritol molecules, and also because an excess of pentaerythritol may drop as a sludge to the bottom of the cooking vessel, interfering with the operation of the stirring means. An alkyd resin, as defined in claim 1, wherein said phthalic acid is terephthalic acid. 1.1 LONG OIL ALKYD RESIN 1. Alkyd Resin – Short oil. Provides adhesion to chalked repaint surfaces when added to exterior latex finishes and can be readily emulsified into latex paint formulations. The viscosity of a 60% solution thereof in 350 mineral spirits is equal to .poises at 25 C. When brushed out in a surface coating, the solution dries dust-free in about 1 hours and tacit-free in about 1% to 2 hours. Alkyd Resin – Long oil. Alkyd resins are poly-esterification products derived from organic acids and alcohols. An alkyd resin consisting of a product of condensation of a phthalic acid, in which the carboxylgroups are separated from each other by at least 3 carbon atoms of the benzene ring and which is free from reactive substituents other than the carboxyl groups, with the product of reaction between pentaerythritol and a material selected from the group consisting of semi-drying oil fatty acids and semi-drying oils, said product of reaction consisting essentially of a mixture of partial esters of polyhydric alcohols from the group consisting of pentaerythritol and glycerol, and containing on the average from 1.5 to 2. (or drthophtlialic acids) has been limited to alkyd resins with oil lengths not exceeding by weight of the resin; because all attempts to modify such resins to higher oil lengths yieldedproducts whose SOILH tions inhydrocarbon solvents displayed low vis cosity and relatively low drying rate, thus being unsuitable for protective surface-coatings. As many apparently widely diiferent embodiments of my invention may be made without departing from the spirit and scope thereof, it is to be understood that this invention is not intended to be limited to the specific examples hereinabove except as defined in the following claims. Hybrid waterborne alkyd–acrylic dispersions with solid content of 40%, free from any surfactant and exempt of any organic solvent, were successfully synthesized by a melt co-condensation reaction between an acrylic prepolymer bearing carboxylic groups and a long-oil alkyd resin.

The term ‘alkyd’ was first used by Kienle in 1927 to describe the reaction products of polyhydric alcohols (AL) with polybasic acids (KYD). Film formation and degradation processes. More specifically, the present invention aims to provide long oil alkyd resin-based paint formulations, wherein the solvent used (i) is essentially free of aromatic and cycloaliphatic hydrocarbons and other impurities, (ii) gives the paint formulation the appropriate viscosity without the need of using viscosity … Immediately after dissolution, it was treated with 5 g of the alkyd resin. Thus, it is seen from the above data that the semi-drying oil-modified alkyd resins, prepared in accordance with my invention from pentaerythritol and isophthalic and/or terephthalic acids and having oil lengths from about 70 to about 80%, are capable of forming solutions in hydrocarbon solvents favorably comparing as regards viscosity and drying rates with alkyd resins prepared from soybean oil, pentaerythritol and phthalic anhydride, and, consequently, are preferable for the purposes of surface-coating industry. A process, as defined in claim 9, wherein said semi-drying oil is soybean oil and said phthalic acid is terephthalic acid. Alkyd resin, is a complex oil-modified polyester that is widely used in a variety of fields involving paints and coatings industry, woodworking, construction, steel sheets, and adhesives. 15. Usually phthalic acid (generally used as the anhydride), 2. However, even in the case of using straight monocarbcxylic fatty acids, it is preferred first to preheat the fatty acids to about 200 C. and then to add thereto the required amount of pentaerythritol, followed. Long oil modified alkyd resins have a wide usage as film forming substances with protection characteristics at anticorrosive paints. The oil length of an alkyd resin is defined as the number of grams of oil used to produce 100 grams of resin. fatty acids, 0.49 mol of pentaerythritol and 0.40 mol of phthalic anhydride for hours at about 25 to 255 C. The acid number of the resulting resin lies between 7 and 8. Applications. Suitable emulsifying agents and special equipment which provide high-energy input are usually required to generate stable oil-in … Alkyd resin, a complex oil-modified polyester that serves as the film-forming agent in some paints and clear coatings.
