聚羧酸系列分散剂在农药水分散粒剂(WDG)中的应用

The Application of Polycarboxylic Series Dispersants in Pesticide Water Dispersible Granule(WDG)

采用清洁的水溶液聚合工艺,以丙烯酸、马来酸和功能单体为主要原料,分别以过硫酸盐、双氧水-金属盐体系、过马来酸体系等为引发剂合成了适宜结构的聚羧酸系列农药分散剂,考察和评价了其对水分散粒剂(WDG)的配伍性及稳定性,并进行了田间药效验证试验,结果表明,其性能达到国内外同类产品水平,具有较好的推广应用价值.

Using aqueous solution polymerization process, the appropriate structures polycarboxylic series dispersants were made from acrylic, maleic acid and functional monomers, in the presence of persulfate, hydrogen peroxidemetal, per-maleic acid as initiators. The stability of compatibility with water dispersible granule （WDG） and the field efficacy trials was studied. The results showed that the property of the water dispersible granule could meet the standards of other products at home and abroad. It is valuable for popularized application.
