500 g/L atrazine aqueous suspension concentrates (SC) were prepared by using sodium salt of methacrylic acid/styrene/sodium p-styrene sulfonate copolymer (SMSS) synthesized with different initiator dosages as dispersants, and the performances of atrazine SC were evaluated. It is found that initiator dosages have remarkable effect on the performance of SMSS. SMSS has higher performance when the initiator dosage is 4.8 wt. %, and the suspensibility of atrazine SC could reach 98.36%, the syneresis rate is only about 0.5% and the particle size is the smallest.
