ABSTRACT:
A laminate comprising (a) a layer of a partially crosslinked graft-modified polyolefin elastomer formed by dynamically heat-treating a mixture of a peroxide-crosslinking olefin copolymer rubber and an olefinic plastic with an unsaturated carboxylic acid or derivative thereof, an unsaturated epoxy monomer or an unsaturated hydroxy monomer in the presence of an organic peroxide and (b) a layer of a polyamide, polyurethane or polyester is excellent in weatherability, heat resistance and dimension stability, and this laminate is effectively molded into an interior part or sealing material of an automobile, especially a glass run channel. The glass run channel molded from this laminate is excellent in the durability, the tightness of contact with glass at the time of closing and the sliding smoothness at the opening-closing operation.
