A mechanistic and laser flash photolysis investigation of acrylamide polymerization photoinitiated by the three component system safranine-T/triethanolamine/diphenyliodonium chloride

Ageing of silorane-based and methacrylate-based composite resins: Effects on translucency

“…19 The non-reacted onium salt have being related to the formation of amine radical. 24 This oxidized tertiary amine works as pigment in the resin matrix. 25 However, if those components are leached from the matrix, it could result in decrease of optical density and, consequently, decreased translucency.…”

Visible light photopolymerization in BHDC reverse micelles. Laser flash photolysis study of the photoinitiating mechanism

“…The most common photoinitiator systems for vinyl polymerization in the visible are composed by a dye and an amine as an electron donor. In our laboratory we have been interested for many years in the mechanistic aspects of PI systems operating in the visible [6][7][8][9]. Here we present results on the polymerization of acrylamide (AA) in reverse micelles of benzyl hexadecyl dimethylammonium chloride (BHDC).…”

Onium salt improves the polymerization kinetics in an experimental dental adhesive resin

“…2 In this way, it is possible that onium salts can also act in the radical polymerization of methacrylates. 3 Several kinds of visible light sensitizer dyes have been investigated, such as safranine, 4 acridine derivatives 3 and acetophenone dyes. 2 In the development of dental adhesives, there are three important reasons to use an onium salt: water-solubility, due The aim of this study was to evaluate the influence of an onium salt in the polymerization kinetics of a dental adhesive model resin.…”
