Abstract

PURPOSE: Granules of a mixture from a specific, thermoplastic, and elastic block copolymer and a styrene resin is soaked with a foaming agent, thus producing formed products showing excellent damping properties against repeated external stress.
CONSTITUTION: Said resin composition is produced by impregnating (I) a granular composition containing a mixture consisting of (a) 100 parts by wt of a thermoplastic and elastic block copolymer of 10,000W500,000 molecular weight, 10W70 wt% of monovinyl aromatic compound content of the formula, (B-S)n, (B-S)n -B or (S-B)m- (B is the lock of conjugated diolefin polymer; S is the block of monovinyl substituted aromatic compound polymer; n is 2W10; m is 1W10), preferrably 1,3-butadiene-styrene or isoprene-styrene, and (b) 25W500 parts of a styrene resin with (II) a foaming agent.
