摘要
Abstract
In this paper,homopolymerization was carried out to prepare polymethyl methacrylate(PMMA)by using methyl methacrylate(MMA)as a monomer and azobisisobutyronitrile as an initiator.The effects of the chroma of MMA,water,and inhibitor contents on the polymerization process and properties of PMMA were investigated.The re-sults indicated that the chroma of MMA should be controlled at below 6 in order to meet a requirement of optical grade for PMMA.There was no direct influence of water content on polymerization.Considering the forming process of PM-MA and avoiding the hydrolysis of PMMA,it was recommended to control water content below 500 mg/kg.When the inhibitor content was less than 10 mg/kg,there was little effect on the polymerization and properties of PMMA,and MMA could be directly used as a monomer for its polymerization.关键词
