PURPOSE:To provide a linear polyester compsn. capable of forming a film having excellent evenness, slipperiness and electrical characteristics, by blending a specified fluoropolymer and a higher aliph. monocarboxylate salt. CONSTITUTION:0.01-10pts.wt. fluoropolymer having a m.p. of 120-255 deg.C, such as polyvinylidene fluoride or a trifluoroethylene/ethylene copolymer, and 0.005- 2pts.wt. C18-C33 higher aliph. monocarboxylate (partial) salt compd., such as magnesium stearate or sodium montanate, are blended with 100pts.wt. polyester mainly composed of ethylene terephthalate repeating units.
