Comparison of techniques for the determination of conversion during suspension polymerization reactions
(Brazilian Society of Chemical Engineering, 2008)
The determination of conversion during suspension polymerization reactions is not an easy task due to the heterogeneity of the reaction medium and the tendency of particles to agglomerate rapidly when stirring is stopped. ...
APPLICATION OF MODEL PREDICTIVE CONTROL TO BATCH POLYMERIZATION REACTOR
The absence of a stable operational state in polymerization reactors that operates in batches is factor that determine the need of a special control system. In this study, advanced control methodology is implemented for ...
Synthesis of PbTiO3 by use of polymeric precursors
(1998-09-01)
Lead titanate powders were synthesized through the use of polymeric precursors according to the Pechini Process. The polymeric precursor was calcined at temperatures ranging from 300 to 600°C for 1 or 2 h. X-ray diffraction ...

Synthesis and characterization of poly-o-toluidine: Kinetic and structural aspects
(2005-01-01)
Poly(o-methylaniline) (poly-o-toluidine, PTOL) was synthesized by chemical oxidation of o-toluidine with ammonium peroxydisulfate in an aqueous 1.0 mol L -1 HCl solution. The progress of polymerization was followed by ...

Kinetics of the free-radical polymerization of isobornyl methacrylate in the presence of polyisobutylenes of different molar masses
(American Chemical Society, 2005-06-11)
The scope of this study was to investigate the effect of a linear polymer dissolved in a reactive monomer on the kinetics of free-radical polymerization before the start of phase separation. The selected system was a ...
