PURPOSE: To provide the titled composition giving an excellent film having improved transparency, flatness and slippery, without causing the clogging of a filter during the melt molding, by compounding a polyester with a specific higher fatty acid amide together with the internal particles containing Ca, etc. n CONSTITUTION: (A) 100pts.wt. of a polyester composed mainly of ethylene terephthalate recurring unit is compounded with (B) 0.001W1.0pts.wt., preferably 0.01W0.5pts.wt. of internal particles containing an element selected from Ca, Mg, Mn, and Li and (C) 0.005W2.0pts.wt., preferably 0.05W0.5pts.wt. of a higher fatty acid amide composed mainly of the 18W33C compounds. The component (C) is e.g. N-stearylamide acetate, etc. n COPYRIGHT: (C)1984,JPO&Japio |
