Abstract
This work describes the kinetics of triethyleneglycol dimethacrylate (TEGDM ) polymerization, photoinitiated by camphorquinone (CQ) / N-phenylglycine ( NPG) and CQ /D,L alpha-phenylglycine (alpha-PG), in air and/or in N-2. The rates of polymerization (R-p), double bond conversion (p), monomer conversi on (p(max)), at different concentration of NPG and alpha-PG were measured a nd analysed. It was found that CQ/NPG is much more effective photoinitiator system than CQ/alpha-PG, regarding to the different their chemical structu re and H-atom donor ability.
