Thermoplastic elastomer composition for calender-molding and sheets prepared therefrom

摘要

A thermoplastic elastomer composition for calender-molding obtained by dynamically heat-treating a mixture comprising 40 to 95% by weight of (A) an oil-extended olefin copolymer rubber containing 100 parts by weight of an olefin copolymer rubber having a Mooney viscosity (ML1+4100° C.) of 120 to 350 and 20 to 150 parts by weight of mineral oil softening agent and 60 to 5% by weight of (B) a polypropylene resin, a process for producing a calendered sheet from the composition and a sheet obtained by the process.
