Poly (ethylene glutarate), poly (ethylene malonate) and poly (ethylene phthalate), were enzymatically synthesized by immobilized Candida antarctica lipase B in solvent free conditions. The synthesis of these polyesters was based on the ester-ester exchange reaction between ethylene glycol diacetate and di-ethyl glutarate, di-benzyl malonate, di-n-octyl phthalate to produce poly (ethylene glutarate), poly (ethylene malonate) and poly (ethylene phthalate), respectively. The effect of ultrasound and PET polymeric beads was evaluated and showed to improve the synthesis of all polyesters. Ultrasound, as a green solvent-free technology, showed high potentiality for the polyester synthesis intensification.
聚（戊二酸乙二醇酯）、聚（马来酸乙二醇酯）和聚（邻苯二甲酸乙二醇酯）是通过固定化南极假丝酵母脂肪酶 B 在无溶剂条件下酶促合成的。这些聚酯的合成是基于乙二醇二乙酸酯和二乙基戊二酸、二苄基丙二酸、二正辛基邻苯二甲酸酯之间的酯-酯交换反应，分别得到聚（戊二酸乙二醇酯）、聚（马来酸乙二醇酯）和聚（邻苯二甲酸乙二醇酯）。评估了超声和 PET 聚合物珠粒的影响，结果表明它们可以促进所有聚酯的合成。超声作为一种绿色无溶剂技术，在聚酯合成强化方面具有很高的潜力。
