摘要
以过硫酸铵为引发剂,在水体系中合成了烯丙醇聚氧乙烯醚、马来酸酐、烯丙基磺酸钠的共聚物WELL-313,研究了聚合反应工艺,确定了反应条件和工艺参数。应用制备的聚羧酸盐分散剂WELL-313搭配WELL-318,按照吡蚜酮悬浮剂的标准进行30%吡蚜酮悬浮分散剂的制备,结果表明所制备的分散剂能够提高制剂的分散性、悬浮率、稳定性等,而且对原药品种有很强的适用性。
The copolymer WELL-313 of SPEG400,MA,ALS with ammonium as initiator in water system.Studied the polymerization process,the reaction and the process parameters were determined.WELL-313 with WELL-318,30%Pymetrozine were preparated in accordance with Pymetrozine suspension standard,the results showed that the preparation of dispersing agent could improve the dispersivity of the preparation,suspension rate,the advantages of stability,and it had strong applicability to the varieties of technical.
