Abstract

PURPOSE: To efficiently product titled polyester, by heat-treating a powder polyester prepared from p-hydroxybenzonic acid (derivative) as the principal starting material by bulk polymerization under a high shearing force and then mechanically pulverizing the heat-treated powder.
CONSTITUTION: A mixture of the following components is bulk-polymerized at 250W870°C under a high shearing force: (A) 100W20mol% hydroxybezoic acid (derivative) containing at least 60mol% p-hydroxybenzoic acid (derivative), (B) 0W40mol% aromatic dicarboxylic acid (derivative) and (C) 0W40mol% aromatic dihydroxy compound (derivative), the mol ratio of component B to component C being about 1. Then, the resulting powdery polymer is heat-treated at 250W400°C in a drying oven or an autoclave and then pulverized by a hammer mill or a roll crusher to product an aromatic polyester having a narrow particle size distribution.
