β¦ Synopsis
Photoinduced reverse and simultaneous reverse and normal initiation (SR&NI) atom transfer radical polymerizations (ATRPs) of methyl methacrylate are investigated. The type and concentration of photoinitiators directly influences the photoinduced reverse ATRP. Although the polymerization can be initiated in the absence of alkyl halide, loss of control over the polymerization process is observed. The photoinduced SR&NI ATRP proceed in a well-controlled manner under UV light at room temperature, as is evident in kinetic and chain extension studies. Better agreement between the experimental and theoretical molecular weights with a narrow molecular weight distribution is observed with photoinduced SR&NI ATRP system.

## Abstract **Summary:** The recently developed initiation system, activators generated by electron transfer (AGET), is used in atom transfer radical polymerization (ATRP) in the presence of a limited amount of air. Ascorbic acid and tin(II) 2βethylhexanoate are used as reducing agents in miniemuls
