摘要：

Bulk polymerizations of methyl methacrylate (MMA) at 60 degrees C initiated with 2,2'-azo-isobutyronitrile are influenced by the presence of an organic pi-donor such as tetrathiafulvalene (TTF). Upon addition of TTF the ratio of weight- to number-average molecular weights <(M)over bar (W)>/<(M)over bar (n)> are significantly reduced and the thermal stability of the poly(methyl methacrylate) samples is increased. Kinetic investigations indicate that TTF acts as a retarder on the polymerization mechanism.
