ABSTRACT:
An olefin thermoplastic elastomer sheet which has the same or similar rubber elasticity, flexibility and molding and processability as those of the conventional olefin thermoplastic elastomer sheets, and is good in mechanical properties and excellent in mar resistance in particular, and a production process thereof, and a laminate having a surface layer composed of this sheet. The olefin thermoplastic elastomer sheet according to the present invention is composed of an elastomer material comprising an olefin random copolymer formed by copolymerizing ethylene, an α-olefin having 3 to 10 carbon atoms and an unsaturated monomer having a functional group, and optionally a non-conjugated diene, and metal ions crosslinking the olefin random copolymer.
