Abstract
PURPOSE: To prepare a polyester containing uniform and fine particles from coarse aggregated particles, by esterifying terephthalic acid with ethylene glycol (or by ester interchange of a terephthalate with ethylene glycol), and by adding the reaction product thus obtained to a slurry of inert inorganic particles in ethylene glycol after a specific treatment, followed by polycondensation.
