Abstract
Compositions comprising poly(alkylene terephthalate), an inert particulate nucleating agent, an oligomeric polyester crystallization promoter, and a segmented thermoplastic copolyester-ether elastomer are disclosed as having improved crystallization behavior and surface appearance. Methods of increasing the crystallization rate of poly(alkylene terephthalate) are also disclosed.
