Abstract

1521870 Polyurethanes PPG INDUSTRIES Inc 17 March 1977 11272/77 Heading C3R An ether-linkage-free polyurethane comprises the reaction product of: (A) a cycloaliphatic polyisocyanate; (B) and (C) active-H- containing materials of M.W.<250, having (B) only 2, and (C)#3, active H atoms per molecule; and optionally (D) a polymeric polycarbonate diol. The equivalent ratio (B)/(C) is from 0À5 to 10. The polyurethane has #20% weight urethane linkages, and calculated M.W. between branch points is 600-4,000.
