Effect of Flasking and Polymerization Techniques on Tooth Movement in Complete Denture Processing
(Wiley-Blackwell, 2009-04-01)
Purpose: The purpose of this study was to compare the artificial tooth positional changes following the flasking and polymerization of complete dentures by a combination of two flasking methods and two polymerization ...
Polymerization Rate Modulated by Tetraarylborate Anion Structure: Direct Correlation of Hammett Substituent Constant with Polymerization Kinetics of 2-Hydroxyethyl Methacrylate
(2018-10-23)
A series of para-substituted tetraarylborates were investigated as aryl radical generator for photopolymerization reactions, using 2-hydroxyethyl methacrylate as monomer. The first steps of the photopolymerization process ...
Effect of multiple feedings in the operation of a high-pressure polymerization reactor for ethylene polymerization
(Taylor & Francis, 2006-08-15)
A thorough model of the high pressure polymerization of ethylene in tubular reactors previously developed by the authors is used to analyze operating conditions for a specific industrial reactor. The objective is to maximize ...
Influence of non-condensable gases on the dynamic behaviour of an auto-refrigerated CSTR polymerization reactor
(Canadian Soc Chemical EngineeringOttawaCanadá, 2006)
Acid catalyst influence on the polymerization time of polyfurfuryl alcohol and on the porosity of monolithic vitreous carbon
(2016-05-20)
This study compares the influence of different acid catalysts on the polymerization rate of polyfurfuryl alcohol (PFA) precursor and especially on the respective porosity of Monolithic Vitreous Carbon (MVC) produced from ...
Process analysis and optimization mapping through design of experiments and its application to a polymerization process
(2011)
The technique of experimental design is used on an ethylene polymerization process model in order to map the feasible optimal region as preliminary information for process optimization. Through the use of this statistical ...
Continuous soluble Ziegler-Natta ethylene polymerizations in reactor trains, 3 - Influence of operating conditions upon process performance
(2008)
The behavior of continuous solution ethylene/but-1-ene polymerizations through Ziegler-Natta catalysts is analyzed, based on a previously developed mathematical model. In order to do that, dynamic simulations are carried ...
