Abstract
We report the synthesis of networked polymers based on the radical ring-opening polymerization of vinyloxiranes. First, the radical ring-opening polymerization of monofunctional 2-phenyl-3-vinyloxirane was investigated. Then, we synthesized di- and trifunctional vinyloxiranes and examined the networked polymer synthesis via the radical ring-opening homopolymerization or copolymerization of these monomers. The obtained networked polymers contained vinyl ether structures in the main chain, which was confirmed by infrared analysis. In addition, we examined the radical ring-opening copolymerization of difunctional vinyloxirane and monofunctional vinyloxirane or adamantane-substituted vinylcyclopropane. Thermal gravimetric analysis revealed that the network formation increased their thermal stabilities.
