The modification plan of horizontal piping pa66 continuous polymerization plants for major domestic and overseas pa66 manufacturers is introduced 摘要介绍了国内外主要尼龙66厂商卧管式连续缩聚装置的改造实施方案。
In this paper , on the basis of intermittent polymerization , twin screw extruder chosen as the reactor , the semi - continuous polymerization of polysulfonamide is investigated 在间歇式聚合的基础上,选用双螺杆挤出机作为反应器,对聚砜酰胺进行了半连续化聚合的研究。
The results show that compared with the intermittent polymerization , the semi - continuous polymerization can greatly improve the reaction rate , and polymer with high relative molecular weight can be easily obtained 研究表明:与间歇式聚合相比,采用双螺杆挤出机进行半连续化聚合可以大大加快反应完成的速度,同时还容易制得相对分子质量较高的聚合物。
