Photopolymerization of vinyl monomers

Polymerization under a magnetic field. VI. Triplet dye-sensitized photopolymerization of acrylamide and methyl methacrylate

“…3,18 -20 Different dyes and reducing agents were used such as methylene blue, thionine, phenothiazine, sodium fluorescein, Dye-sensitized photopolymerization of vinyl monoriboflavin, etc., as dyes and triethanolamine, mers was the subject of extensive investigations ascorbic acid, para-substituted benzene sulfinate in 1950s and 1960s. 1 It was first reported by Bamions, etc., as reducing agents. Among these studford and Dewar 2 for styrene, by Oster and coies, the methylene blue sensitized photopolymerworkers for acrylamide and other vinyl monomers, 3,5 by Palit and co-workers for methyl methization of acrylamide in presence of a reducing acrylate, 6,7 and by other investigators.…”

The Role of Vinyl Groups and Quaternary Amino Groups on Microgel Particle Surface in Photopolymer System.

“…[14] In this procedure, these Rps are calculated from the decrease in the IR absorption monitored at 810 cml which assigned C-H perpendicular vibration of vinyl groups. [17][18][19][20][21] 3. Results…”

Stepwise Photopolymerization of Bichromophoric Chains by Cycloaddition of Dibenz[b,f]azepine Groups

“…The photopolymerization of a bichromophoric compound was examined quantitatively. In this system, the degree of conversion, p, is represented as: (1) where N 0 is the number ofbifunctional OC-10 molecules at the initial time, and N, that after irradiation time t. The total number of cyclobutane rings formed during irradiation time t, is N 0 -N. Since two terminal OBA groups are consumed for each intermolecular cycloaddition reaction, the total number of consumed OBA groups is represented as 2 (N 0 -N). In this bichromophoric compound, the number of terminal OBA groups is 2N 0 at the initial state.…”
