Abstract

1391066 Urethane oils IMPERIAL CHEMICAL INDUSTRIES Ltd 23 June 1972 [16 July 1971] 33458/71 Heading C3R Urethane oils are prepared by reacting a partial ester of a polyhydric alcohol and an unsaturated carboxylic acid with a mixture of 3 - isocyanatomethyl - 3,5,5 - trimethylcyclohexyl isocyanate and isocyanurate polyisocyanates derived therefrom, in amount such that the number of isocyanate groups does not exceed the number of hydroxyl groups in the ester. The partial esters are most preferably prepared from a polyhydric alcohol containing more than two OH groups and unsaturated fatty acids derived from drying oils. The isocyanurate polyisocyanates may be obtained from the monomeric diisocyanate by polymerization in the presence of an alkali metal phenate as catalyst. Coatings may be produced by dissolving the urethane oils in a solvent which contains an oxidation catalyst and applying the solutions to a substrate. In an example a partial ester is produced from safflower oil and pentaerythritol and reacted with the polyisocyanate mixture.
