Abstract
PURPOSE: A polyester film, prepared by dispersing a polysulfone compound in a granular form in a polyester, and having improved slipperiness, abrasion resistance and wear resistance.
CONSTITUTION: A film, consisting of a polyester, and prepared by dispersing a granular polysulfone compound, 50wt% or more of which has a diameter ≤3μ, in an amount of 0.05W3wt%, preferably 0.05W1wt%, therein. The polysulfone compound preferably contains at least one of the repeating units expressed by formulasIWIII as main constitutent units.
