  • Abstract

    Biodegradable copolymer microsphere poly (ECH-co-NVP) was synthesized by a ring-opening polymerization process of Epichlorohydrin and N-vinyl-2-pyrrolidone.The copolymerization of Epichlorohydrin (ECH) and N-vinyl-2-pyrrolidone (NVP) catalyzed by Maghnite-H+ (Mag-H+) was investigated. The effect of some factors such as the amount of the catalyst (Maghnite-H+) and the temperature of reaction. It was found that the copolymerization rate increased with increase in the temperature and the proportion of catalyst, and it was larger in nonpolar solvents. The product was characterized by various technic characterizations such as FTIR and 1H-NMR.
