Synthesis of Isobutyl Vinyl Ether-maleic Anhydride and Its Application in Preparation of Chlorpyrifos Microcapsules

LIU Shu-jing et al(College of Science,Agricultural University of Hebei,Baoding,Hebei 071001)  
[Objective] The aim was to prepare pesticide sustained-release microcapsules with isobutyl vinyl ether-maleic anhydride as emulsifier.[Method] Isobutyl vinyl ether-maleic anhydride copolymer was synthesized by aqueous solution polymerization,and then mixed with Tween-80 in the preparation of microcapsules.[Result] The results showed that compound emulsifier had better emulsifying effect,and the microcapsules had regular and compact surface.The drug loading was 62.10%,and entrapment efficiency was 95.64%.[Conclusion] The study provides a theoretical basis for development and application of pesticide microcapsules.
