Thermal degradation of visible-light-cured thiol-methacrylate networks photoactivated with camphorquinone
(Elsevier, 2017-02-08)
This report describes the yellowing of visible light-cured thiol-ene networks formulated with Camphorquinone (CQ) as photoactivator. CQ displays an intense dark yellow color due to the presence of a conjugated diketone ...
Visible light polymerization of epoxy monomers using an iodonium salt with camphorquinone/ethyl-4-dimethyl aminobenzoate
(John Wiley & Sons Ltd, 2013-01-16)
A visible light initiator system for the photoinduced cationic polymerization of epoxymonomers is reported. The system consists of camphorquinone (CQ) in combination with ethyl-4-dimethyl aminobenzoate (EDMAB) and a ...
Photoinitiation rate profiles during polymerization of a dimethacrylate-based resin photoinitiated with camphorquinone/amine. Influence of initiator photobleaching rate
(Pergamon-Elsevier Science Ltd, 2009-02-12)
The photodecomposition of camphorquinone (CQ)/amine during the photo polymerization of a dimethacrylate-based resin under continuous irradiation was investigated in thick samples. The global CQ photoconsumption was measured ...

Effect of Camphorquinone Concentration in Physical-Mechanical Properties of Experimental Flowable Resin Composites
(Hindawi Ltd, 2018)
The aim of this study was to evaluate the effect of camphorquinone concentration in physical-mechanical properties of experimental flowable composites in order to find the concentration that results in maximum conversion, ...
Silsesquioxanes functionalized with one or two side-chain amino groups as coinitiators of camphorquinone in photoinitiated polymerization of methacrylate monomers
(European Centre for Nanoestructured Polymers, 2012-10-16)
Organotrialkoxysilanes (APS-PGE2) and (DAS-PGE3) were synthesized by reacting 1 mole of 3-(aminopropyl)triethoxysilane (APS) with 2 mole of phenylglycidylether (PGE) or 1 mole of N-(β-aminoethyl)-γ-aminopropyltrimethoxysilane ...
