Dye-sensitized photopolymerization: II—Photopolymerization of methyl methacrylate initiated by a Crystal Violet-ascorbic acid system in aqueous solution

Abstract

The dye-sensitized photopolymerization of methyl methacrylate by a Crystal Violet-ascorbic acid system in aqueous solution was investigated. The systems were buffered with phosphate buffer and the effects of monomer, dye, temperature, buffer and ascorbic acid on the reaction system were studied. The rate of polymerization was measured gravimetrically and a suitable kinetic scheme has been proposed.
