WERKWIJZE VOOR HET HECHTEN VAN EEN VOORWERP VAN EEN GE- VULCANISEERDE EP- OF EPA-COPOLYMEERRUBBER AAN EEN POLYALKEENKUNSTSTOF.

摘要

A method for bonding rubber to plastics by contacting a vulcanized shaped structure of an ethylene/propylene copolymer rubber or an ethylene/propylene/diolefin copolymer rubber with a polyolefin plastic at a temperature above the softening point of said polyolefin plastic, said vulcanized shaped structure consisting of a blend of (i) 60 to 97 % by weight of an ethylene/propylene copolymer rubber having an ethylene content of 40 to 85 mol% or an ethylene/propylene/diolefin copolymer rubber having an ethylene content of 40 to 85 mol% and 0 to 100 %, based on the weight of the copolymer rubber, of a rubber component other than the above copolymer rubbers and a butyl rubber, and (ii) 3 to 40% by weight of specific crystalline polyethylene or polypropylene plastic.
