ABSTRACT

In this paper, we used neopentyl glycol as a comonomer to participate in the reaction with poly(ethylene terephthalate), and synthesized poly(ethylene terephthalate-co-neopentyl glycol) polyester samples. Through a series of tests, we found that the crystallization ability of the copolymer is closely related to the content of comonomer. Self-nucleation and annealing thermal fractionation were first used to study copolymer, as well as non-isothermal crystallization kinetics analysis were also employed to estimate how neopentyl glycol contents affected the crystallization ability of copolymer. With the increase of neopentyl glycol content, the crystallinity, crystalline rate, Avrami exponent of copolymer changed obviously. Besides, X‑ray diffraction was also used to study the crystalline structures of samples. Results showed that the crystalline of the copolymer have not been changed by the variety of neopentyl glycol content. More... »
