Abstract
The photopolymerization of methylmethacrylate (MMA) with methyl viologen (MV2+)-Na2S2O4-CCl4 initiator was studied in aqueous-organic two-phase system. The initial rate (Rp) of photopolymerization was proportional to the square root of fed quantity of initiator components, MV2+, Na2S2O4, and CCl4, respectively. Rp, however, decreased when MV2+ or CCl4 was fed beyond a certain value. Rp also gradually decreased in the presence of a large excess of CCl4. A cyclic phase-transfer initiation system has been proposed for this photopolymerization on the basis of MV+ยท cation radical disproportionation.
