Rubber material with barrier material made of cycloolefin copolymers

摘要

A rubber material is described, modified with a barrier material in the form of a copolymer which can be produced via 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.

主权项

1. A process for modifying a rubber material, comprising applying a copolymer to a rubber material or introducing the copolymer into the rubber material, wherein the copolymer is obtained by ring-opening metathesis polymerization of
at least one olefin monomer selected from the group consisting of a monocyclic olefin monomer having one or two endocyclic C—C double bonds and a bicyclic olefin monomer having one endocyclic C—C double bond, and a polycyclic olefin monomer having at least two C—C double bonds, and wherein the modifying comprises at least one selected from the group consisting of impregnating, spraying, spreading, coating, and calendering.
