Abstract

PURPOSE: To obtain the title composition containing particles well dispersed therein which can give a film excellent in slidability, winding property and abrasion resistance, by dispersing specified spherical silica microparticles in a polyester based on ethylene 2,6-naphthalate units.
CONSTITUTION: An alkoxysilane compound (a) (e.g., tetramethoxy-silane) is hydrolyzed and polycondensed in the presence of an amine catalyst (b) (e.g., ammonia) to obtain a spherical silica microparticles (B) which are substantially amorphous and have a mean particle diameter of 0.01W3.0μm and a particle diameter distribution satisfying the formula [wherein (d10/d90) is a ratio of the particle diameter corresponding to 10% cumulation of particles to the particle diameter corresponding to 90% cumulation of particles]. The title composition is obtained by dispersing 0.001W5wt.% component B in a polyester (A) containing at least 80mol.%, desirably, at least 90mol.%, ethylene 2,6-naphthalate units. This composition is extruded into a sheet at 280W320°C and quenched to 80°C or below to form an amorphous sheet, and this sheet is oriented at an area draw ratio ≥4 in both the longitudinal transverse directions and further heat-treated at 120W250°C to obtain a biaxially oriented film of a thickness of 0.2W300μm.
