本工作根据 Pepper的反应机理,对电子转移引发的阴离子聚合反应以及单体链转移对这一反应的影响等问题作了理论处理,求得了分子量分布函数的精确解。对于以乙烯基(艹米)为单体、萘-钠为引发剂、四氢呋喃为溶剂的反应体系,理论计算的结果和已报道的实验数据基本相符。 According to the reaction mechanism of Pepper, this work theoretically dealt with the problem of the anionic polymerization initiated by electron transfer and the influence of monomer chain transfer on this reaction, and obtained the exact solution of the molecular weight distribution function. For the reaction system with vinyl (艹 m) as monomer, naphthalene-sodium as initiator and tetrahydrofuran as solvent, the theoretical calculation is in good agreement with the reported experimental data.
