Abstract
Chemically blended thermoplastic interpenetrating polymer network compositions, of improved physical and mechanical properties as compared to their mechanically blended counterparts, are produced by forming a solution or mixture of polymeric components and polymerizing in situ, with materials capable of forming physical crosslinks, through mechanisms including block copolymers, ionomeric crosslinking and the incorporation of crystalline regions in semicrystalline homopolymers. The resultant products are in the nature of thermoset materials at room temperature but become thermoplastic at elevated temperatures.
