Study on Synthesis and Release Behavior of Controlled Release Combinations Pesticide-Cellulose Esters

摘要

Pesticide-cellulose esters as controlled release combinations were prepared. Pesticide containing carboxyl or hydroxyl group linked to macromolecular carriers, cellulose or carboxymethylcellulose through ester bond. The degree of substitution of pesticide bonded to the carrier, could be adjusted by varying the reaction conditions. The pesticide-polymer so prepared could degrade and release pesticide spontaneously when exposed to water and showed bioactivity in bioassay.
