| 摘要 |
<p>Styrene-butadiene block copolymer thermoplastic rubber compositions are bonded to other surfaces, such as polyvinyl chloride, leather, canvas and the like, by (1) coating the surface of the block copolymer composition and/or the other surface with a primer, which is an organic solvent solution of a graft copolymer of a styrene-butadiene block copolymer and an alkyl methacrylate, (2) applying an adhesive to both surfaces and (3) pressing the surfaces together for a time sufficient to obtain a suitable bond. This invention is of particular value in preparing shoes using styrene-butadiene block copolymer soling materials.</p> |
