MULTILAYERED COMPOSITE MATERIAL AND PRODUCTION THEREOF

摘要

PURPOSE:To provide a multilayered composite material integrally constituted of a base material comprising a bulk ring opening polymer due to a metathesis catalyst system of a norbornene monomer and a layer forming material made of a synthetic resin especially excellent in the adhesiveness with a polyvinyl chloride resin. CONSTITUTION:A multilayered composite material is constituted by integrally forming a polyolefinic resin layer and an ethylene/vinyl acetate copolymer layer on a base material composed of a bulk ring opening polymer due to a metathesis catalyst system of a norbornene monomer in this order and produced by supplying a reactive raw solution containing the metathesis catalyst system of the norbornene monomer into a mold having the laminate of the polyolefinic resin layer and the ethylene/vinyl acetate copolymer layer arranged therein as a layer forming material to subject the same to bulk ring opening polymerization.
