Abstraet--Bis-acetylacetonato-iron(ID initiates a slow radical polymerization of styrene in bulk above 40 Β° . The order of reaction with respect to initiator is low and decreases to zero as the initiator concentration increases. The overall rate of polymerization obeys the Arrhenius equation in the
Atom transfer radical polymerization conditions with copper(I) bromide/pentamethyldiethylenetriamine (CuBr/PMDETA) as the catalyst system were employed for the polymerization of tert-butyl acrylate, methyl acrylate, and styrene to generate welldefined homopolymers, diblock copolymers, and triblock c
