Abstract
A polyester urethane is prepared from (A) one mol of a linear hydroxyl terminated polyester of a saturated aliphatic glycol having 2-10 C and a dicarboxylic acid HOOC-R-COOH where R is an alkylene radical of 2-8 C, or the anhydride of the acid, the polyester having a M.W. of 600-2000 and an acid number of less than 10; (B) 1.3-3.0 mols of a diphenyl diisocyanate having an -NCO group on each phenyl nucleus (C) 0.3-2.0 mols of a saturated aliphatic diol having 2-6 C, the molar amount of (A) and (C) combined being equivalent to the molar amount of (B); by (a) reacting one mol of the polyester with 40-85 mole per cent of the total amount of diphenyl diisocyanate to form a prepolymer, (b) mixing the remainder of the diphenyl diisocyanate with the prepolymer and (c) reacting the mixture with the diol.
