摘要：A new type of dispersant for pesticide water dispersible granules (WDGs), sodium salt of methacrylic acid/styrene/sodium allylsulfonate copolymer (SMSA) was synthesized. 90 wt% atrazine WDG was prepared to evaluate the dispersion performances of SMSA. It is found that SMSA has high performance and strong resistance to hard water, and the suspensibility of 90 wt% atrazine WDG before and after hot storage could reach 93.14% and 92.22% in standard hard water, and 87.19% and 85.33% in three-fold standard hard water, respectively.
