摘要
本文叙述了以涤纶废丝为原料,通过醇解改性共缩聚的方法研制聚酯热熔胶的试验过程和结果,讨论了在聚酯热熔胶的大分子中引入醚键,以达到提高其柔顺性和粘合性能的目的。
A heat-meltable adheslve obtained by alcoholysis modlfication and copolymerizatlon of wastepolyester thread is developed.Experimental procedure:and resuIts obtained are described. Effects ofintroducing ether bond to the large molecules of the adhesive to improve the flexibility and adhesiveness isalso discussed.
