摘要(Abstract)：

以不同的稀土金属元素化合物及稀土化合物/三氧化二锑复合物分别用作聚酯酯交换和缩聚催化剂,对各工艺参数进行分析,并对产品性能进行测试与表征。结果表明:稀土化合物可作为聚酯酯交换的催化剂和缩聚助催化剂;使用稀土化合物/三氧化二锑复合催化剂,能有效提高酯交换效率,缩短反应时间,降低酯交换开始温度,所得聚酯产品的色相优于普通三氧化二锑催化所得聚酯,结晶度比普通三氧化二锑催化所得聚酯的高,且重稀土有机化合物比轻稀土无机化合物催化效率更高。
Rare-earth compound and rare-earth/Sb_2O_3 complex catalysts for polyester transesterification and polycondensation by DMT route were studied.Also the properties of polyesters and process parameters were analyzed.The results showed that rare-earth compound was used as catalysts for polyester transesterification and associate catalysts for polyester polycondensation.Rare-earth compound/Sb_2O_3 complex catalyst could enhance the reaction efficiency,reduce the reaction time and lower initial temperature of transesterification. At the same time,the L value and crystallization capabilities of polyester by rare-earth compound/Sb_2O_3 complex catalyst was higher than stibium compound catalysts.Efficiency of polyester catalyzed by heavy organic rare-earth compound-was better than light inorganic rare-earth compound.
