RUBBER MATERIAL WITH BARRIER MATERIAL MADE OF CYCLOOLEFIN COPOLYMERS

摘要

A rubber material is described, provided with a barrier material in the form of a copolymer preparable by ring-opening metathesis polymerization of a) at least one olefin monomer selected from the group consisting of monocyclic olefin monomers having one or two endocyclic C-C double bonds and bicyclic olefin monomers having one endocyclic C-C double bond, and b) at least one polycyclic olefin monomer having at least two C-C double bonds. The barrier material can be used to reduce the gas permeability of the rubber material.
