Gencoglu, Turkan published the artcilePhotoinitiating systems based on poly(ethylene imine) for Michael addition and free radical photopolymerization, Application of Ethyl 4-dimethylaminobenzoate, the publication is Journal of Photochemistry and Photobiology, A: Chemistry (2021), 112959, database is CAplus.
Multifunctional polymeric photoinitiators with the ability of aza-Michael addition with acrylates, free radical polymerization of (meth)acrylates through type II photoinitiation and charge transfer complex (CTC) formation with iodonium salt (Iod) were prepared They were synthesized via aza-Michael addition reaction between branched poly(ethylene imine) (PEI, Mn =1800 g/mol), 2-acryloyloxy thioxanthone and tetra-Et vinylidene bisphosphonate or di-Et vinylphosphonate. Their structures were confirmed by 1H NMR and FTIR spectroscopy. CTC formation between Iod (acceptor) and amines on PEI (donor) was confirmed by absorption shift to 440 nm in spectral anal. Photopolymerization kinetics were monitored by real time FTIR upon visible light exposure using LED @405 nm, whereas Michael addition reactivities of the photoinitiators were monitored without irradiation Excellent polymerization initiating performances were found and high final conversions were obtained. Results show that the CTCs formed at high concentrations of low-functionalized PEI allow polymerizations without light and increase polymerization efficiencies of Type II photoinitiation.
