Cases for memory disks having excellent antistatic properties

摘要

A case for memory disks having excellent antistatic properties, which comprises a thermoplastic resin composition comprising 100 parts by weight of the following component (A), 3 to 30 parts by weight of the following component (B) and 5 to 40 parts by weight of the following component (C): component (A): a crystalline propylene resin having a melt flow rate (MFR) of 1 to 80 g/10 min; component (B): a thermoplastic elastomer selected from (b1) olefin copolymer elastomers having a Mooney viscosity (ML1+4 (100 DEG C.)) of 10 to 85, and (b2) hydrogenated products of a block copolymer of styrene or a derivative thereof and a conjugated diene, containing 15 to 50% by weight of styrene or a derivative thereof, having a weight-average molecular weight of 50,000 to 220,000; and component (C): an acrylamide copolymer.
