Abstract
PURPOSE: To obtain a molding material capable of forming a transparent, colorless, thick, hollow polyester molding with a high productivity, by using a Mn-Ge-Co-P catalyst and also by specifying ranges of the relative viscosity and content of isophthalic acid.
CONSTITUTION: A molding material for hollow polyester moldings contains a Co compound, a Mn compound, a P compound, and a Ge compound in amounts meeting formulas IWIII and consists of an ethylene terephthalate-based copolyester with a relative viscosity of 1.6W2.3 and an isophthalic acid content of 5.0W20.0mol% (based on total acid components). The said copolyester is obtained by a procedure in which definite amounts of dimethyl terephthalate and dimethyl isophthalate, for example, are mixed, subjected to ester exchange reaction with ethylene glycol in the presence of a Mn compound, and then subjected to polycondensation reaction by the addition of a Co compound, a P compound, and a Ge compound.
USE: Containers for cosmetics, foods, and beverages.
