摘要
Abstract
The changes in solvent composition after multiple cycles of solvent use in self-stable precipitation polymerization of α-methylstyrene/maleic anhydride were studied.The effects of reused solvent on chemical composition,morphology,particle size and its distribution of polymer microspheres were investigated.The experimental results show that the impurities in raw materials and polymers dissolved in solvent are increased with the increase of solvent used times.The chemical composition of polymers are not affected with the repeated use of solvent,and the product is still spherical particles.The yield and size of polymer change with the reuse of solvent,and the diameter dispersion index remains below 1.02.关键词
