Polymer Networks with Antibacterial Activity by UV Photopolymerization
The crosslinking by radical UV photopolymerization of mixtures of acrylic oligomers added with 2,4,40 -trichloro-20 -hydroxydiphenyl ether (TCDPE) allows to obtain polymer films which perform like hygienic coatings. The ...
Visible light photoinitiating systems: Toward a good control of the photopolymerization efficiency
(Technical Association of Photopolymers, 2010-06)
This paper discusses the photochemistry of three-component photoinitiating systems (3K-PIS) for free radical photopolymerization and the efforts made during the last decades to propose efficient systems applied to the laser ...
The Effect of the Mixtures of Photoinitiators in Polymerization Efficiencies
(JOHN WILEY & SONS INC, 2009)
The photoinitiated polymerization of methyl methacrylate using the mixtures of camphorquinone (CQ) and acylphosphine oxides (monoacylphosphine oxide, MAPO or bisacylphosphine oxide,BAPO) was studied to determine the possible ...
Magnetic molecularly imprinted polymers obtained by photopolymerization for selective recognition of penicillin G
(2020-04-05)
Some of the most important life-saving medications are β-lactam antibiotics (such as Penicillin G). However, these medicines have not adequately been discharged into the environment; penicillin residues offer health risks ...
Effect of metal oxide fillers in urethane dimethacrylate polymer with glycerol obtained by photopolymerization synthesis
(2020-10-01)
Urethane dimethacrylate (UDMA) is a monomer widely used in photopolymerization reactions to produce biomaterials, due to its advantageous properties such as mechanical resistance and relatively low viscosity. However, this ...
High-Performance Photoinitiating Systems for Free Radical Photopolymerization. Application to Holographic Recording
(Wiley, 2013-08)
The photoinitiating systems (PIS) usable in free radical photopolymerization are briefly reviewed. Apart conventional Type I and Type II photoinitiators, three-component photoinitiating system exhibiting a photocyclic ...
Monitoring of visible light photopolymerization of an epoxy/dimethacrylate hybrid system by Raman and near-infrared spectroscopies
(Elsevier, 2013-08-11)
Hybrid systems formulated with epoxy and methacrylate monomers at mass fraction either 50:50 or 75:25 were studied. The individual monomer conversions during photopolymerization with visible light were monitored by Raman ...

Microhardness of dual-polymerized resin cement around a translucent fiber post in the intraradicular environment
(2011-10-01)
Aim: In this study, we evaluated the effect of photopolymerization on Vickers microhardness of dual-polymerized resin cement at three locations when a translucent quartz fiber post was used. Materials and Methods: Single-rooted ...
