Abstract

PURPOSE: To obtain a polyester containing many finely divided uniform particles, by adding an ethylene glycol sourry wherein finely divide calcium carbonate and potassium (magnesium) salt of a fatty acid are dispersed to a polyester preparation system.
CONSTITUTION: Finely divided calcium carbonate having an average particle diameter not more than 7μ (preferably containing almost no coarse particle with particle diameters not less than 15μ, having particle size distribution with sharp increase in smaller particle side) and about 1W50 wt.% based on the calcium carbonate of calcium (magnesium) salt of 1W4C fatty acid are dispersed in ethylene glycol to form a slurry. In polymerization, the slurry in an amount to give about 0.05W5 wt.%, preferably 0.1W2 wt.% based on a formed polyester of the finely divided calcium carbonate is added to a polyester preparation system.
