Abstract
The present invention relates to a process for forming composite shaped articles used for athletic shoe soles, tubes, pipes, transmission belts and conveyor belts, comprising a vulcanized elastomer directly or autogenously bonded, that is, essentially in the absence of adhesive, to a thermoplastic elastomer comprising recurring polyamide-6 and polyether structural units, such as thermoplastic polyetheresteramide elastomers, are provided. The article is prepared by a process comprising placing a thermoplastic elastomer component into a vulcanization mold, overmolding onto at least a portion of the surface area of one face surface of the thermoplastic elastomer component with a vulcanizable elastomer component, and vulcanizing the vulcanizable elastomer component at a temperature below the melting point of the thermoplastic elastomer component but over a wide temperature range, which can be about 40° C. or higher.
