Abstract
PURPOSE: To obtain the title polyester having improved color and a high polymerization degree readily, by using a specific amount of a glycol-soluble titanium compound and titanium dioxide as a polymerization catalyst and a pigment, respectively.
CONSTITUTION: (A) A glycol-soluble titanium compound, e.g. titanium tetramethoxide, in an amount expressed by formula I [[Ti] is the number of moles of the titanium compound added per mole of the acid component] as a catalyst and (B) titanium dioxide in an amount expressed by formula II [[TiO2] is wt% of titanium dioxide based on the formed polyester] as a pigment are used to satisfy formula III [[P] is the number of moles of the glycol-soluble phosphorus contained in titanium dioxide to be added] in preparing a polyester consisting mainly of terephthalic acid.
