PURPOSE:The titled compsn. keeping excellent antistatic performance semipermanently and having an excellent antistatic property even after weight reduction working, which comprises a thermoplastic polymer, polyoxyalkylene glycol (deriv.) and specified vinyl polymer. CONSTITUTION:A vinyl polymer is obtd. by polymerizing (a) a vinyl monomer such as styrene, (b) at least 3mol% vinyl-base unsaturated sulfonic acid (or sulfonate) such as sodium p-styrenesulfonate and (c) at least 1mol% unsaturated aliph. carboxylic acid alkyl ester in which the alkyl group has 1-15 carbon atoms such as methyl (meth)acrylate. Then at least one thermoplastic polymer such as polyethylene terephthalate, 0.1-10wt%, based on the total of (a) and (b), polyoxyalkylene glycol (deriv.) of weight-average M.W.>=1,000 and the above vinyl polymer in such an amt. as to contain 0.5-18wt%, based on the total of (b) and (c), component (a) are compounded. |
