Synthesis of sodium salt of Poly(acrylic acid-maleic anhydride) dispersant And in 75 thifensulfuron WDG application

摘要

The sodium salt of Poly(acrylic acid-maleic anhydride) was prepared by solution polymerization method and applied to 75% thifensulfuron WDG. The results show that granule suspension rate all achieves 85% above, disintegrating time is less than 60 seconds, thermal decomposition rate is less than 3%. That meet WDG various technical indicators.
