早在50年代,Jordan et al就用稳态法处理过极性单体的阴离子型聚合反应,得到分子量分布与单体转化率无关的结论。后来,Lohr又用近似方法对瞬时引发、单体终止的聚合反应作了非稳态处理。本文作者之一[4]最近推广Lohr的反应方程,对多官能度引发剂瞬时引发并有单体链终止的聚合反应进行了非稳态分析,得到分子量分布函数和其它分子 As early as the 1950s, Jordan et al treated the anionic polymerization of polar monomers by the steady-state method and got the conclusion that the molecular weight distribution was unrelated to the monomer conversion. Later, Lohr again approximated the instability of the transient initiated, monomer-terminated polymerization. One of the authors of this paper [4] recently promoted Lohr’s reaction equation to conduct an unsteady analysis of the polymerization initiated transiently with multifunctional initiator and with monomer chain termination to obtain the molecular weight distribution function and other molecules
