摘　　要：用氧化还原引发体系和复合乳化剂进行了乙酸乙烯酯 ( VA c)的低温乳液聚合 ,讨论了聚合温度对聚合速率、聚合度的影响以及转化率与聚合度的关系。对聚乙酸乙烯酯的甲醇溶液的粘度和溶液浓度、聚乙烯醇 ( PV A)The low\|temperature emulsion polymerization proceeded in the circumstance of oxidation\|reduction initiator and composite emulsifier. The effects of polymerization temperature on the rate and degree of polymerization,and the relationship between monomer conversion and polymerization were discussed.Moreover, the relationship between the viscosity or concentration of methanol solution for polyvinyl acetate and polymerization degree was also discussed.
