非腈复合引发剂用于乙酸乙烯溶液聚合
Non-nitrile compound initiator used for vinyl acetate solution polymerization
摘要
Abstract
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.关键词
