Abstract

1376839 Polyurethanes PECHINEY UGINE KUHLMANN 11 July 1972 [12 July 1971] 32407/72 Heading C3R Polyurethanes, which contain in the same molecule alternating sequences of urethane units derived from polyester polyols with sequences derived from polyether polyols and with certain -NCO terminal units, are prepared by first preparing a polyether polyurethane prepolymer with a substantial excess of polyisocyanate and then reacting the resultant prepolymer with at least one polyester polyol in such a proportion that the product still contains -NCO functionality. The polyether may be a triol obtained from propylene oxide and glycerol. The polyester may be derived from a lactone or from adipic acid and butane diol. The polyisocyanate may be tolylene diisocyanate or diphenylmethane diisocyanate. Reaction may take place (both steps) in solution, e.g. in dimethylformamide or dimethylsulphoxide. Uses: coating compositions.
