Abstract
PURPOSE: To obtain a polyester having improved color, thermal stability, and operating efficiency in molding in a short time, by using a specific catalyst in the direct polymerization.
CONSTITUTION: An aromatic dicarboxylic acid is esterified with a glycol in the presence of (A) an antimony and/or a germanium compounds, (B) a cobalt compound, (C) a bivalent metallic compound consisting of magnesium, calcium, manganese, and zinc, and (D) a phosphorus compound in a molar amount of 0.7W5 times that of the total (B) and (C). The reaction mixture is then polycondensed. The preferred amounts of (A), (B), and (C) are 0.01W0.1mol%, 0.001W0.02 mol%, and 0.002W0.05mol%, based on the dicarboxylic acid, respectively.
