Abstract
The present invention relates to a polybutylene terephthalate composition and the manufacturing method thereof. The change rate of crystallization heat flow of the polybutylene terephthalate composition is greater than 200 mW/g-min, and the change rate of crystallization heat flow is determined according to the method of ISO 11357-3:2018. The polybutylene terephthalate composition of this invention has ideal heat resistance and low impurity content, and it is highly applicable in subsequent processing.
