摘要： The present invention relates to a process for preparation of polyester resin in the presence of a novel catalyst system comprising an antimony compound and inorganic tin compound. The present invention also relates to a catalyst system for the- preparation of polyester comprising an antimony compound and inorganic tin compound which reduces the polymerization time at all stages of polyester synthesis and reduces the generation of degradation product. This invention further relates to polyester resin with improved L color having significant importance in end-use applications.
摘要翻译： 本发明涉及一种用于在一个新的催化剂体系，包含锑化合物和无机锡化合物的存在制备的聚酯树脂的方法。 因此，本发明涉及一种催化剂体系用于聚酯的，包括锑化合物和无机锡化合物在哪的聚酯合成所有阶段减少了聚合时间，降低的降解产物的产生的制备。 本发明还涉及与具有最终用途应用显著重要性提高的L-色聚酯树脂。
