以生物乙烯法生产的乙酸乙烯为单体、过氧化月桂酰-十二烷基二甲基叔胺为非腈复合引发剂、甲醇为溶剂进行溶液聚合反应的研究。实验考察了反应温度、反应时间、甲醇用量、引发剂用量对反应产物聚合率和聚合度的影响，采用正交试验优化了乙酸乙烯溶液聚合的反应条件，确定反应因素对聚合率和聚合度影响的相对大小。结果表明，最优的乙酸乙烯溶液聚合条件为：反应温度65℃，反应时间3h，甲醇用量10%，引发剂用量0.010%，获得聚乙烯醇产品的聚合度为3776，聚合率为45.29%。直观分析确定影响聚合率的因素主次顺序为引发剂用量﹥反应时间﹥甲醇用量﹥反应温度；影响聚合度的因素主次顺序为甲醇用量>引发剂用量>反应温度>反应时间。

Solution polymerization was studied using vinyl acetate made by biological ethylene as monomer,lauroyl peroxide-dodecyl dimethyl tertiary amine as non-nitrile compound initiator, methanol as solvent. Influences of reaction temperature,reaction time,dosage of methanol,and dosage of initiator on polymerization exponent and the degree of polymerization were investigated. Reaction condition of vinyl acetate solution polymerization was optimized,and influence extent of factors affecting polymerization exponent and degree of polymerization was determined by using orthogonal experimental design. The results show that the optimum polymerization condition is as follows:reaction temperature 65℃,reaction time 3h,dosage of methanol 10%,dosage of initiator 0.010%. Poly (vinyl alcohol) was obtained,degree of polymerization is 3776,and polymerization exponent is 45.29%. The influence extents of these factors for polymerization exponent are in following order:dosage of initiator>reaction time>dosage of methanol>reaction temperature. The influence extents of these factors for degree of polymerization are in following order:dosage of methanol>dosage of initiator>reaction temperature>reaction time.
