聚酯缩聚催化剂用量的控制

Control of catalyst amount in polyester polycondensation

缩聚催化剂会对聚酯后加工性能产生不良影响。选择溶解性能好的催化剂 ,降低酯化残存羧基量 ,提高缩聚温度 。

Polycondensation catalyst may has bad effect on polyester afterprocessing properties.The amount of catalyst can be reduced by selecting nice solvability catalyst,cutting down the remnant carboxyl amount of esterification and elevating polycondensation temperature.
