Abstract

PURPOSE: To prepare the title compound suitable for the molding of a thin-walled article with high dimensional accuracy, by adding polyethylene wax or polypropylene wax to the reaction system before the completion of the polymerization of polybutylene terephthalate.
CONSTITUTION: A polybutylene terephthalate molding compound having a relative viscosity of 1.3W1.75, is prepared by adding a polyethylene wax and/or a polypropylene wax having a molecular weight of 500W12,000 to the polymerization reaction mixture of polybutylene terephthalate at an arbitrary stage before the completion of the polymerization. The amount of the wax is 0.01W2.0wt% based on the prepared polybutylene terephthalate.
