ABSTRACT:
Polyalkylene arylate resin compositions include a crystalline polyalkylene arylate base resin and a copolyester comprised of a polyalkylene arylate segment which exhibits smectic liquid crystallinity, and a polyalkylene arylate segment which does not exhibit smectic liquid crystallinity. Improved crystallization rates, and thus faster mold cycle times (i.e. increased productivity), ensue from the compositions of this invention.
