Polycycloolefin (PCO) thermoset assembly and process for its preparation

摘要

The present invention relates to a polycycloolefin (PCO) thermoset network assembly obtainable by polymerising a first reactive composition comprising a norbornene-type cycloolefin monomer in the presence of a Mo- or W-catalyst to obtain a PCO-Mo/W-network and polymerising a second reactive composition comprising a norbornene-type cycloolefin monomer in the presence of Ru-catalyst on said PCO-Mo/W-network to obtain a PCO thermoset network assembly.
