研究了有机锰试剂[R3 Mn] - Li +（R=Bu，Me）在叔丁醇钾存在下对甲基丙烯酸甲酯的催化作用。将引发剂中的R基团由Bu改为Me后，所得聚甲基丙烯酸甲酯的立构规整度由杂同立构（mr = 54%）转变为全同立构（mm = 58%），三异丁基铝的加入有效地控制了所得聚合物的Mw和Mw/Mn。
Organomanganate reagents [R 3 Mn] - Li + (R=Bu, Me) were found to polymerize methyl methacrylate in the presence of potassium tert-butylate. A conversion of the tacticity of the resulting poly(methyl methacrylate)s from heterotactic (mr = 54%) to isotactic (mm = 58%) was observed upon changing the R group of the initiator from Bu to Me. The addition of triisobytylaluminium was found to efficiently control M w and M w /M n of the resulting polymers.
