Wu, YinPing published the artcileNew acyl phosphine oxides as high-performance and low migration type I photoinitiators of radical polymerization, Application of Trimethylolpropane triacrylate, the publication is Progress in Organic Coatings (2022), 106876, database is CAplus.
Two low migration acylphosphine oxide photoinitiators (APO and DAPO) containing unsaturated C=C double bonds have been designed and synthesized for free radical polymerization The properties and performances of APO and DAPO in the free radical polymerization of trimethylolpropane triacrylate (TMPTA) were evaluated and compared with the com. photoinitiator 2,4,6-trimethyl(phenyl) di-Ph oxide (TPO). The results show that DAPO exhibited the best double bond conversion (DC) of TMPTA in the photoinitiators tested under the same reaction conditions. The migration ratio of APO and DAPO was 2/3 and 1/3 of that of TPO resp. indicating lower migration than the conventional photoinitiator, and the solubility of DAPO in monomers was close to that of TPO, which provided the possibility for the industrial application of DAPO.
