A process for preparing novel polymers having interpenetrating networks comprising polymerizing simultaneously a mixture of a bicyclic amide acetal, a polyisocyanate and a vinyl monomer component is described.
摘要:
Polymerizable solutions of mixtures containing a bicyclic amide acetal, a polymer which does not react with the bicyclic amide acetal and a monomer or polymer capable of undergoing condensation polymerization with the bicyclic amide acetal, a process for polymerization of such solutions and the novel polymers resulting from the polymerization are described.
