ISOCYANATE-REACTIVE COMPOSITIONS COMPRISING A POLYMER HAVING A PLURALITY OF 3-(SUBSTITUTED AMINO)-2-ALKENOYLOXY GROUPS EACH HAVING ONE OF THE AMINE SUBSTITUENTS CONTAINING AT LEAST ONE ISOCYANATE-REACTIVE GROUP; PREPARATION AND USE THEREOF

摘要

The invention is concerned with an isocyanate-reactive composition comprising a polymer having a molecular weight of at least 500 containing a plurality of groups of the formula : CHEM wherein R1 represents hydrogen or a hydrocarbon radical; R2 represents a hydrocarbon radical; R3 represents an organic radical carrying at least one isocyanate-reactive group, and R4 represents hydrogen or an optionally substituted hydrocarbon radical. Such compositions are useful for making moulded elastomers and flexible foams.
