OLEFINIC THERMOPLASTIC ELASTOMER SHEET, PROCESS FOR PRODUCTION THEREOF, AND LAMINATES

摘要

An olefinic thermoplastic elastomer sheet which is equivalent to current olefinic thermoplastic elastomer sheets in rubber elasticity, flexibility, a nd fabrication quality and exhibits good mechanical characteristics, particular ly excellent mar resistance; a process for producing the same; and laminates comprising the sheet as the surface layer. The sheet is made from an elastomeric material which comprises both an olefinic random copolymer obtained by copolymerizing ethylene with an .alpha.-olefin having 3 to 10 carbon atoms, an unsaturated monomer having a functional group, and, if necessary, a nonconjugated diene, and a metal ion for crosslinking the rando m copolymer.
