新型共聚酯(PARSTER~)的连续聚合生产技术

Continuous Polymerization Technology of New Co-Polyester(PARSTER~)

通过分析新型共聚酯(PARSTER?)中第三单体间苯二甲酸二甲酯-5-磺酸钠(SIPM)和第四单体二甲基-1,3-丙二醇(MPD)的特性及参与反应的方式,确定了PARSTER?生产的工艺设计。根据工艺设计的要求,通过设备改造及工艺调整,实现了PARSTER?在10万t/a聚酯连续生产线上的稳定生产,得到了性能指标合格的产品。

By analyzing characteristic and reaction way of the third monomer （SIPM） and the fourth monomer （MPD） in the new co-polyester （PARSTER ）, the production process design of PARSTER is set up. According to requirements of process design, the stable production of PARSTER is realized on the 100 000 t/a polyester continuous production line and quality product is obtained through equipment modification and process adjustment.
