Abstract
PURPOSE: To provide the title molded article for food container, having decreased whitening tendency and low aldehyde content, made of a polyethylene terephthalate prepared by the polycondensation of the monomers in the presence of Ti and Ge catalysts and magnesium stearate.
CONSTITUTION: A polyester blow molded article having an intrinsic viscosity of 0.5W1.0 and containing 20W200ppm of magnesium stearate (as Mg), 5W15ppm of a titanium compound (as Ti) and 10W100ppm of a germanium compound (as Ge), is made of a polymer obtained by the polycondensation of a glycol ester of a dibasic carboxylic acid composed mainly of terephthalic acid and/or its oligomer, in the presence of (A) magnesium stearate, (B) a titanium compound such as titanium alkoxide, and (C) a germanium compound such as germanium oxide or germanium alkoxide.
