PURPOSE:To prepare a polyester compsn. which gives a film excellent in the abrasion resistance, slipperiness, surface properties, and transparency by compounding specific org. particles into a polyester, thereby keeping the specific resistance of the polyester, when it is fused, in a specified range. CONSTITUTION:0.001-10wt.% particles with a mean particle diameter of 0.01-5mum obtd. by coating the surface of particles comprising a crosslinked polymer (e.g. a polymer of methyl methacrylate, divinylbenzene, and etylvinylbenzene) with a copolymer having in its side chain a vinyl monomer unit with a benzene ring (e.g. styrene) and an acrylic acid deriv. unit (e.g. polyammonium acrylate) is compounded into a polyester (e.g. polyethylene terephthalate), and thus the specific resistance of the polyester, when it is fused, is kept in 1.0X10<6>-1.0X10<9>OMEGA.cm. |
