Temperature Effects in Conventional and RAFT Photopolymerization.

ABSTRACT: Photochemical processes are often thought to be temperature-independent. However, photochemical polymerization involves photochemical processes such as light-driven radical generation coupled with thermal-driven reactions such as monomer propagation. The apparent activation energy of propagation, E _A(R _p), of a series of three monomers, methyl acrylate (MA), methyl methacrylate (MMA), and styrene (STY), are deduced from Arrhenius analysis of conventional and RAFT photopolymerization of these monomers across a range of corresponding temperatures. The deduced E _A(R _p) was compared with the benchmarked E _A(k _p) derived from pulse laser polymerizations coupled with size exclusion chromat
