Abstract
PURPOSE: To prepare a polyester having a high softening point, improved moldability and color, by polycondensation of a glycol ester and/or its low polymer of an aromatic dicarboxylic acid in the presence of a catalyst comprising a Ti and a specific P compounds.
CONSTITUTION: One or more types of glycol esters of aromatic dicarboxylic acids or their low polymer or both are polycondensed in the presence of a catalyst comprising (a) 0.001W0.05mol% calculated as Ti of a Ti compound of the formula Ti(OR)4 (R is alkyl group) and (b) 0.5W5.0 moles per mole of (a) of a P compound of the formula (R1, R2, and R3 are H or alkyl groups, and two or more of them are ≥10C alkyl groups).
