ABSTRACT:
In accordance with the present invention, there is provided a process for preparing thermoplastic elastomer laminates which comprises placing a thermoplastic elastomer foamable sheet in an unexpanded state containing a polyolefin resin, an ethylene/.alpha.-olefin copolymer rubber and a foaming agent onto the back of a thermoplastic elastomer sheet containing a polyolefin resin and an ethylene/.alpha.-olefin copolymer rubber, heat fusion bonding both sheets to each other, and heating the resulting laminated sheet to expand the thermoplastic elastomer sheet containing the foaming agent.
