PURPOSE:To prepare the title film having uniform surface projections with few coarse projections and excellent slipperiness, running properties, etc., by compounding poly-p-phenylene sulfide with two kinds of inert fine particles each in a specified amt. CONSTITUTION:Poly-p-phenylene sulfide is compounded with 0.05-2wt.% first component comprising inert fine particles A having a mean particle diameter ratio (major diameter to minor diameter) of 1.0-2.5, a mean particle diameter of 0.01-2.0mum, and a relative standard deviation of particle diameter expressed by equations I and II [wherein Di is an equivalent diameter (mum) of equal-area circle of each particle; D is a mean equivalent diameter (mum) of equal-area circle; and n is the number of particles] of 1.0 or lower (e.g. vaterite CaCO3), and 0.01-1wt.% second component comprising inert fine particles B having a mean particle diameter ratio of 1.0-2.5 and a mean particle diameter of 1.5-3.0 times that of the particles A (e.g. vaterite CaCO3). |
