Abstract
A process for the preparation of polyurethanes comprises reacting (a) an organic diisocyanate with (b) an hydroxyl polyester of acid number below 10 and hydroxyl number below 224 and prepared by condensing a dicarboxylic acid having at least 3C with a glycol containing at least one secondary hydroxyl group in the molecule or a mixture of glycols, at least one of which contains at least one secondary hydroxyl group in the molecule and a polyhydric alcohol having the formula R(OH)n where R represents an organic radical after the removal of the hydroxyl groups from a polyhydric alcohol and n is 3, 4 or 5 wherein, when n is 3, the polyhydric alcohol is used in an amount from 0.003 to 0.75 mol. per equivalent of secondary hydroxyl groups, when n is 4, the polyhydric alcohol is used in an amount from 0.0015 to 0.0375 mol. per equivalent of secondary hydroxyl groups and when n is 5, the polyhydric alcohol is used in an amount from 0.001 to 0.025 mol. per equivalent of secondary hydroxyl groups, and (c) a difunctional chain-extending agent of MW less than 500 and containing hydroxyl and/or amino groups; the diisocyanate being employed in amount to provide an -NCO to OH ratio of greater than 1. Chain-extending agents may be: dihydric alcohols, hydrazines, hydrazides, diamines and amino alcohols. Many suitable alcohols and acids for the preparation of the polyester are listed. Isocyanates listed include aliphatic, cycloaliphatic, aromatic and sulphur and halogen containing isocyanates. In a typical Example (1) a polyester derived from adipic acid, propylene glycol, ethylene glycol and trimethylolpropane was mixed with 1,4-butanediol and 4,41-diphenyl methane diisocyanate added.
