Mechanistic aspects of maleimide-donor photocopolymerizations
Chemistry, Multidisciplinary; Chemistry, Physical; Polymer Science
The relative rates in the alternating copolymerization of a difunctional maleimide and conventional alkenyl ether have been investigated and compared to the exomethylenic aryl(alkyl)dioxolane, 4-methylene-2-phenyl-1,3-dioxolane, using real-time infrared (RTIR) spectroscopy. The mechanistic differences in propagation between the two donors have been examined and evaluated by laser flash photolysis. It is shown that structural modifications which increase the electron density in the vinylic C=C bond produce higher rates of copolymerization. Copolymerization studies indicate that the relative extent of ring opening decreases with increasing temperature.
