CYCLOOLEFIN RESIN CURED PRODUCT HAVING OXYGEN BARRIER PROPERTIES

Document Type and Number:

WIPO Patent Application WO/2022/045204

Kind Code:

A1

Abstract:

Provided is a cycloolefin resin cured product having oxygen barrier properties, the cycloolefin resin cured product being obtained by bulk polymerization of a polymerizable composition containing a cycloolefin monomer and a metathesis polymerization catalyst. The cycloolefin monomer contains a norbornene-based monomer (a). The antioxidant content of the polymerizable composition is 0.3 mass% or less. The oxygen permeability at 23°C is less than 50 mL/m2･day･atm (100 μm).
