Photopolymerization of MMA at 35 was studied using benzophenone (BP)-dimethylaniline (DMA) combination as photo-redox initiator. Initiator exponent was 0.13: monomer exponent was < 1.0 in chlorinated solvents and > 1.0 in other solvents. Photoreduction of BP by DMA is considered to produce chain-ini

A combination of Michler's ketone and benzoyl peroxide was used as photoinitiator for photopolymerization of methyl methacrylate at 40". Spectrophotometric analysis indicated equilibrium complexation between the initiator components; the complex is considered to be the actual initiating species, giv
