Abstract:
1. A method of coaxially bonding a polymeric tube to a prefabricated tubular body defining a hollow central tubular passage having a longitudinal axis bounded by an inner wall that is comprised of one or more of a polycarbonate, an acrylic or a copolymer containing an acrylonitrile, the method comprising: coextruding an outer tubular layer comprised of an ethylene copolymer functionalized with a conjugated vinyl moiety together with at least one inner tubular layer comprised of a thermoplastic elastomeric material to form a mating tube having an outer surface comprised of the functionalized ethylene copolymer, a central tubular passage having a longitudinal axis and opposing ends, treating the outer surface of the mating tube along a selected axial length of at least one of the ends with an alcohol or ketone or a UV or visible light curable containing material that causes the treated outer surface to adhere to the inner wall of the tubular body on curing or drying, inserting the treated end of the mating tube coaxially into the central tubular passage of the tubular body such that the outer surface of the treated end mates with the inner wall of the tubular body along the selected axial length to form a mated juncture, curing or allowing the mated juncture to dry such that the treated outer surface bonds to the inner wall.
