摘要
以长链二元酸和二无醇为反应单体,采用熔融缩聚的方法合成了聚酯,对合成产物进行了红外吸收光谱(FTIR)、核磁共振氢谱(1HNMR)和凝胶色谱(GPC)等表征。研究了醇酸比、反应单体、催化剂种类、催化剂用量、抽真空时间等因素对合成产物结构的影响。
Polyesters were synthesized by long-chain diacids and diols using melting condensation reaction. The synthetic products were characterized by fourier transform infrared (FTIR), ^1H NMR and gel permeation chromatography (GPC). The effects of the ratio between diol and diacid, monomers, catalyst category, catalyst content and vacuuming time on the molecular structure of the synthetic products were also investigated in this paper.
