A study on kinetics and mechanism of the anionic equilibrium polymerization of α-methylstyrene α-甲基苯乙烯阴离子平衡聚合动力学及反应历程研究
Introducing crosslink agent VTMS could change linear polysiloxane into crosslinked elastic network and influence the equilibrium of the condensation reaction of end-hydroxyl polysiloxane by inhibiting inverse reaction. The polymerization was speeded up as well. 交联剂VTMS的引入,不仅使线性聚硅氧烷形成交联的弹性体网络,而且改变了端羟基硅氧烷的缩合平衡反应速率,抑制了逆反应,加快了聚合速率。
The equilibrium molecular weight of the polymer was lower than that of the polymer from conventional emulsion system at the same polymerization temperature, and the effect of temperature on the molecular weight was little. 相同反应温度下生成的聚合物的平衡分子量低于常规乳液聚合,且温度对分子量的影响不如常规乳液聚合明显。
