Design of networked polymers based on radical ring-opening polymerization of vinyloxiranes

We synthesized difunctional and trifunctional vinyloxiranes and investigated the synthesis of networked polymers via the radical ring-opening homopolymerization or copolymerization of these monomers. The obtained networked polymers contained vinyl ether structures in the main chain, as confirmed by infrared analysis. In addition, we investigated the radical ring-opening copolymerization of monofunctional vinyloxirane or adamantane-substituted vinylcyclopropane. Networked polymers with various crosslinking densities were obtained, and the heat resistance and volume change of these polymers were evaluated before and after curing.
