REACTION INJECTION MOLDED BODY HAVING COATING FILM ON SURFACE AND METHOD FOR PRODUCING SAME

摘要

A reaction injection molded body having a uniform coating film over the entire surface can be easily produced by obtaining a molded body through bulk polymerization of a polymerizable composition within a mold and then forming a coating film on the surface of the molded body within the mold by an in-mold coating method. The polymerizable composition contains a norbornene monomer, a polymerization catalyst and an inorganic filler composed of a fibrous filler having an aspect ratio of 5-100 and a particulate filler having an aspect ratio of 1-2.
