摘要
使用3种不同的催化剂Sb2O3、SbAc3和自制的复合催化剂合成聚酯树脂,本文对比了3种催化剂对缩聚反应时间和加工过程中粘度损失的影响,提出使用复合催化剂可以显著提高产品的白度,以满足在包装领域的实际应用要求。
Used three kinds of the different activators such as anmonous oxideicantimony acetate and home-made composited activator as synthetic poly ester resin, this paper compared 3 kinds of activa- tors with condensation polymerization time and the influence of viscidity losing in the processing, pointed out using the composited octavator can Increase the whiteness obviously, to meet with the practical application requirement of packing aera.
