发明名称 POLYESTER COMPOSITION, ITS PRODUCTION AND FILM THEREFROM
摘要 PROBLEM TO BE SOLVED: To obtain a polyester composition containing inert particles which include extremely small amount of spherical coarse particles, and further to provide a method for producing the composition, and to obtain a film composed of the polyester composition. SOLUTION: This polyester composition containing inert particles having average particle diameters within the range of 0.2-0.1μm has <=100/1,000,000 existence probability of spherical coarse particles having >=2μm particle diameters and 1.0-1.2 particle diameter ratio, based on the whole inert particles.
