PURPOSE:To bond rubber firmly with a simple operation, by using a thermoplastic polyester block copolymer as an adhesive in bonding an acrylonitrile/ butadiene rubber to various vulcanized rubbers with heating. CONSTITUTION:A rubber selected from among an epihalohydrin rubber, a chlorinated polyolefin rubber, an acrylic rubber and an acrylonitrile/butadiene rubber before or after vulcanization is bonded to an acrylonitrile/butadiene rubber with heating by using a thermoplastic polyester block copolymer as an adhesive. Said block copolymer is a copolymer composed of a high-melting polyester segment and a low-melting polymer segment having an MWof 400-6000 and is used in sheet or film form of 0.1-1mm. |
