PURPOSE:To obtain a polyester composition improved in the balance between easy slidability and transparency, by adding specified crosslinked particles to a polyester. CONSTITUTION:12wt.% pure divinylbenzene is added to styrene, and the mixture is polymerized to obtain crosslinked PS particles (B) of a heat decomposition temperature (10% weight loss) according to a thermobalance >=380 deg.C, a mean particle diameter of 0.01-5mum and a volume shape factor of 0.35-0.52. 0.001-10wt.% component B is added to a polyester comprising (A) a bifunctional acid component based on an aromatic dicarboxylic acid (esterifiable derivative) and at least one glycol component. |
