PURPOSE:To provide the titled compsn. having durable antistatic properties imparted thereto without detriment to inherent physical properties, by blending a given amount of a specified vinyl polymer with a thermoplastic polymer. CONSTITUTION:A vinyl polymer composed of at least 0.1mol% of a monomer unit (a) consisting of an unsaturated vinyl compd. having a polyoxyalkylene chain having an average MW of 200-5,000 (e.g. a polyoxyalkylene glycol acrylate), at least 1mol% of a monomer unit (b) consisting of an unsaturated vinylsulfonic acid (salt) (e.g. styrenesulfonic acid) and 0-98.9mol% of other unsaturated vinyl compd. (c) (e.g. vinyl acetate), is used. Said vinyl polymer is blended with a thermoplastic polymer such as a polyester in such an amount that the amount of the monomer unit (a) accounts for 0.1-10wt% of the entire compsn. |
