Procedure

PPT was produced by ester exchange reaction and polycondensation reaction of dimethyl terephthalate and 1,3-propanediol. Then, an aqueous slurry of aluminum silicate particles was prepared, which particles were synthesized by reacting sodium silicate and sodium aluminate in an aqueous system by a wet method and had an aluminum ratio of 20% by weight in terms of aluminum oxide. This aqueous slurry was mixed with and kneaded in PPT pellets.
