摘要

Abstract

Poly(butylene terephthalate)-poly(tetramethylene glycol) (PBT-PTMG) copolymer is prepared with terephthalic acid (PTA) rather than its dimethyl ester (DMT) as starting material by a two-step melt polycondensation. This process includes the synthesis of PBT prepolymer from PTA with 1

4-butanediol (BDO) in the first step

followed by the synthesis of PBT-PTMG copolymer from PBT prepolymer with PTMG in the second step. The molecular weight

composition as well as thermal and mechanical properties of the products from the two-step melt polycondensation are compared with the properties of the PBT-PTMG from the traditional one-step melt polycondensation. When the PTMG content is low

there is only slight difference in molecular weight

composition

thermal and mechanical properties among PBT-PTMG copolymers obtained from these two methods. However

when the PTMG content is high

only the two-step strategy is able to give high molecular weight products

and the products have comparable thermal and mechanical properties with those from traditional one-step strategy using DMT as starting material.
