PURPOSE:To provide titled composition capable of making film of high transparency, smoothness and lubricity, incorporated with each specified amount of both internal and inert partials of respective specific size and specific higher fatty acid compound. CONSTITUTION:The objective composition can be obtained by incorporating (A) 100pts.wt. of polyester consisting mainly of polyethylene terephthalate with (B) 0.005-2 (pref. 0.01-5)pts.wt. of fine particles with a size pref. 0.1-2mu (internal particles derived from adding Ca-, Mg-, and/or Li-compound plus, pref. P-compound, in the form of glycol solution, to the polycondensation system; and inert particles added, in the form of water and/or ethylene glycol-dispersed slurry, to the system during or prior to the polymerization) and (C) 0.005-2 (pref. 0.05-0.5)pts.wt. of 10-33C (pref. 20-32C) higher aliphatic monocarboxylic acid (ester) compound (e.g. carnauba wax). |
