摘要：The present invention relates to a thermoplastic elastomer composition havinga three-dimensional network structure which is not formed by a chemical crosslinking andhaving an excellent elasticity recovery and flexibility, a foam having a highly closed cell, anuniform cell shape, an excellent elasticity recovery, flexibility and appearance, and aprocess for producing the same. A thermoplastic elastomer of the invention is obtainedby mixing in a predetermined ratio an EPDM (1), a crystalline polyethylenic resin (2) and ablock copolymer (3) having a crystalline ethylenic polymeric block and a block which ismore compatible with said EPDM than with said crystalline polyethylenic resin togetherwith an anti-aging agent followed by kneading in a pressurized kneader. A foam of theinvention is obtained by adding 1 part by mass of a wetting agent to 100 parts by mass ofthe thermoplastic elastomer composition described above together with a foamingagent, agitating and then performing an extrusion foaming.
