ABSTRACT:
A high strength conduit for carrying potable water at temperatures of up to about 180.degree. F. comprising a first tubular member having a mating end portion formed from polyvinyl chloride, a second tubular member having a mating end portion also formed from polyvinyl chloride, telescopically received in the mating portion of the first tubular member, a cured adhesive composition joining said mating end portions of the first and second tubular members. The cured adhesive composition is formed from a curable composition comprising a minor proportion by weight of a thermoplastic elastomeric copolymer comprising from about 40 to about 97 weight percent of recurring units of a monovinyl aromatic monomer, from about 1 to about 30 weight percent of recurring units of an .alpha.,.beta.-unsaturated dicarboxylic acid anhydride, from about 1 to about 30 weight percent of recurring units of an .alpha.,.beta.-unsaturated carboxylic acid, and from about 1 to about 40 weight percent of recurring units of a C.sub.1 -C.sub.4 alkyl ester of methacrylic acid. On the basis of 100 parts of the thermoplastic elastomeric copolymer of (a), from about 1 to about 35 parts by weight of an elastomer comprising a block copolymer of butadiene and styrene is also included. The composition also includes major proportion by weight of reactive solvent for the thermoplastic copolymer, such as methyl methacrylate monomer, and a catalyst for said reactive solvent.
