发明名称 POLYTRIMETHYLENE TEREPHTHALATE AND PROCESS FOR PRODUCING THE SAME
摘要 The present invention provides a poly(trimethylene terephthalate) comprising 80% by weight or more of trimethylene terephthalate units based on the entire repeating units, having an intrinsic viscosity of from 0.4 to 1.5 dl/g, and satisfying the following formula (1): (1)  Ä-OHÜ/(Ä-OHÜ + Ä-COOHÜ + Ä-CH2CH=CH2Ü) x 100 >/= 40 wherein Ä-OHÜ, Ä-COOHÜ and Ä-CH2CH=CH2Ü represent a terminal hydroxyl group content, a terminal carboxyl group content and a terminal allyl group content of the poly(trimethylene terephthalate), respectively, and a process for producing the poly(trimethylene tereplhalate). <IMAGE>
