Abstract

Polymeric material comprising an interpenetrating network of a polyol(allyl carbonate), e.g., Nouryset.RTM.200, epoxy resin. The polymeric material is prepared by polymerizing 70 to 95 parts by weight of the polyol(allyl carbonate) by radical initiation and polymerizing partially or entirely simulataneously an epoxy resin-forming mixture by acid catalysis. The epoxy resin-forming mixture comprises 10-90 wt. % of aliphatic or cycloaliphatic polyepoxide and 90-10 wt. % of a polyol/anhydride adduct having molecular weight of 500-5,000.
