Abstract
PURPOSE: To obtain a polyester having excellent color tone, excellent heat resistance, and improved workability for molding by esterification of an aromatic dicarboxylic acid and glycol over a catalyst composed of a Sb and/or Ge compound and a divalent metal (e.g., Mg) compound followed by polycondensation reaction with a phosphorus compound.
CONSTITUTION: In the esterification of an aromatic dicarboxylic acid and glycol followed by polycondensation reaction for the manufacture of polyester, a catalyst consisting of 0.003W0.5mol%, as metallic atom based on the dicarboxylic acid component, of an Sb compound and/or a Ge compound (A) and 0.001W0.05mol%, as metallic atom based on the dicarboxylic acid component, of one or more of divalent metal (Mg, Ca, Mn and Zn) compounds is used for esterification, and then a phosphorus compound in a molal amount 0.7W5 times as much as the aforesaid divalent metal compound is added to polycondensation reaction system.
