METHOD FOR PRODUCING NORBORNENE RESIN LAMINATE

摘要

PROBLEM TO BE SOLVED: To provide a method for producing a norbornene resin laminate which can laminate norbornene resin layers different in physical properties simply and efficiently by subjecting a norbornene monomer to bulk ring-opening polymerization. SOLUTION: The method includes a process in which a reaction liquid (1) containing a norbornene monomer (1) and a metal-carbene complex (1) is injected into a molding mold (1) and subjected to the bulk ring-opening polymerization to form the fires norbornene resin layer and a process in which a reaction liquid (2) containing a norbornene monomer (2) and a metal-carbene complex (2) is injected into a molding mold (2) and subjected to bulk ring-opening polymerization to laminate the second norbornene resin layer on the first norbornene resin layer. The composition of the reaction liquid (1) is different from that of the reaction liquid (2).
