Claim 2
Dependent Claim
96 words
A process for preparing a polymer having good impact resistance at a rapid rate comprising interpolymerizing a mixture of a bicyclic amide acetal, a polyamine containing two or more amine groups per molecule having at least two amino groups per molecule which have at least one hydrogen capable of reaction with isocyanates and a polyisocyanate wherein the weight ratio of amide acetal to polyamine is in the range of from 95:5 to 5:95 and the equivalent ratio of isocyanate to combined bicyclic amide acetal and polyamine is in the range of from 0.8:1 to about 3:1.
