Photopolymerization-assisted self-assembly as a strategy to obtain a dispersion of very high aspect ratio nanostructures in a polystyrene matrix
(Pergamon-Elsevier Science Ltd, 2018-10)
Very high aspect ratio nano-objects dispersed in a polymer matrix impart a number of desired characteristics to the material, such as barrier properties to the diffusion of small molecules. Commonly, these dispersions are ...
Analysis of polymerization time on abrasive wear of dental resins
(Universidade Federal de São Carlos (UFSCar), Dept Engenharia Materials, 2010-01-01)
An evaluation was made of the abrasive wear of six composite thermofxed dental resins subjected to different polymerization times. The method of evaluation was based on sharpness measurements to quantify the abrasive wear ...

Photopolymerization of N,N-dimethylaminobenzyl alcohol as amine co-initiator for light-cured dental resins
(Elsevier, 2008-05)
Objective: The present study was carried out in order to assess the suitability of N,N-dimethylaminobenzyl alcohol (DMOH) as co-initiator of camphorquinone (CQ) and 1-phenyl-1,2-propanedione (PPD) in light-cured dental ...
Visible light photopolymerization in BHDC reverse micelles: laser flash photolysis study of the photoinitiating mechanism
(Elsevier Science, 2013-02)
The photopolymerization of acrylamide (AA) in reverse micelles (RMs) of benzyl hexadecyl dimethylammonium chloride (BHDC) was investigated. The polymerization was performed by irradiation in the 500 nm region of the spectrum, ...
Optimization of a photopolymerizable material based on a photocyclic initiating system using holographic recording
(Royal Society of Chemistry, 2012-11)
A set of photoinitiating systems (PIS) for free radical photopolymerization was studied using time-resolved spectroscopic experiments, real-time FTIR and holographic recording. It is shown that the efficiency of the ...
Evaluation of Postpolymerization as a Function of the Storage Time of Triethylene Glycol Dimethacrylate/2,2-Bis[4-(2-Hydroxy-3-Methacryloxy-Prop-1-Oxy)-Phenyl]-propane Bisphenyl-alpha-Glycidyl Ether Dimethacrylate Copolymers Used in Dental Resins by Differential Scanning Calorimetry and Dynamic Mechanical Analysis
(JOHN WILEY & SONS INC, 2009)
The aim of this work was to evaluate the effect of the storage time on the thermal properties of triethylene glycol dimethacrylate/2,2-bis[4-(2-hydroxy-3-methacryloxy-prop-1-oxy)-phenyl]propane bisphenyl-alpha-glycidyl ...
Pyrromethene derivatives in three-component photoinitiating systems for free radical photopolymerization
(John Wiley & Sons Inc, 2010-06)
1,3,5,7,8-pentamethyl pyrromethene difluoroborate complex (HMP) and 2,6-diethyl-8-phenyl-1,3,5,7-tetramethylpyrromethene difluoroborate complex (EPP) were used to initiate the polymerization of a diacrylate in a two- and ...
Photopolymerization of methacrylate monomers using polyhedral silsesquioxanes bearing side-chain amines as photoinitiator
(Elsevier, 2011-12-11)
Organotriethoxysilanes (APS-PGE2) were synthesized by reacting 1 mol of 3-(aminopropyl) triethoxysilane with 2 mol of 1,2-epoxy-3-phenoxypropane (PGE). Polyhedral oligomeric silsesquioxanes functionalized with bulky amino ...
