Abstract

A method for the preparation of a urethane modified ethylenically unsaturated vegetable oil having drying properties is characterized by reacting a diisocyanate and a diol system comprising a diol ester of an ethylenically unsaturated vegetable oil and 3 to 18% based upon the weight of the diol ester of a diol in which the hydrocarbon groups are separated by not more than 4 carbon atoms and having a molecular weight of less than 120, the amount of diisocyanate employed being substantially equivalent to the total hydroxyl of the diol system and the amount of diol ester being sufficient to produce a final oil length of 30 to 80%, the reaction being continued under heating until the resultant urethane modified oil possesses substantially no free isocyanate. The reaction is usually performed in an inert organic solvent, and may be effected in two stages, the addition of reactants and first heating taking place below 130 DEG F. and the final stage at above 130 DEG F. Linseed, safflower, perilla, tall and soybean oils are specified vegetable oils. Glycerine, pentaerythritol and trimethylol propane or ethane are suitable polyols for the preparation of the diol ester. In examples (1) a modified drying oil is produced as a semi-solid by reacting a diol ester (from linseed oil and pentaerythritol), propylene glycol (or a butane diol) and tolylene diisocyanate; (2) a similar reaction is effected in aromatic or mineral spirits solvent solution; (3) similarly reacted are a diol ester (from pentaerythritol, glycerine and distilled tall oil fatty acids), 2,4-pentanediol and tolylene diisocyanate in xylene solution; (4) a dihydroxy ester (from soybean oil and pentaerythritol), 1,3-butylene glycol and tolylene diisocyanate are reacted.
