Abstract
A process for preparing novel interpolymers from mixtures of a bicyclic amide acetal, an oxazoline and a polyisocyanate and the novel polymers produced are described.
Claims19
The process for preparing a tough, high-softening polymer comprising interpolymerizing a bicyclic amide acetal, an oxazoline and a polyisocyanate at a temperature in the range of from about room temperature up to about 200.degree. C. and at a pressure in the range of from about atmospheric up to about 100 atmospheres.
