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-2pyrrolidone (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
