Abstract

Organomanganate reagents [R3Mn]–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 triisobutylaluminium was found to efficiently control M̄w and M̄w/M̄n of the resulting polymers.
