PURPOSE:To obtain the subject composition excellent in an antistatic effect with its persistence and in color by using a thermoplastic resin and a specified (meth)acrylic ester copolymer as the constituents each in a specified amount. CONSTITUTION:The resin composition contains 100 pts.wt. thermoplastic resin (e.g. PP) and 3-30 pts.wt. (meth)acrylic ester copolymer consisting of linearly arranged 65-99mol% polyolefin structural units of formula I (wherein R<1> is H or CH3), 0-15mol% (meth)acrylate structural units of formula II (wherein R<2> is R<1>; and R<3> is 1-12C alkyl) and 1-35mol% (meth)acrylic ester structural units of formula III (wherein R<4> is R<1>; R<5> is 2-8C alkylene; R<6> and R<7> are each 1-4C alkyl; R<8> is R<3>, 6-12C arylalkyl or 6-12C alicyclic alkyl; and X is halogen, CH3OSO3 or C2H5OSO3) and having a weight-average molecular weight of 1,000 to 50,000. |
