Letter

Poly(trimethylene terephthalate) (PTT) has received considerable attention recently as potential important fibers and engineering thermoplastics owing to its outstanding characteristics such as high elastic recovery, chemical resistance and resilience [1, 2, 3]. As a typical semicrystalline polymeric material, the applicability and processing condition of PTT are determined by its thermal properties and crystallization behavior. Much studies have focused on this topic [4, 5, 6, 7]. In a previous paper, we also carried out the kinetics analysis of PTT crystallization including the secondary crystallization process using a new mathematical model constructed by us [7]. Furthermore, copolymerization using several amounts of a second glycol or diacid comonomer is an approach frequently used to attain new linear thermoplastic polyesters with modified thermal properties. However, so far there’s been little reported on the modification of the thermal properties of PTT by copolymerization....
