Fluidized bed reactor for polyethylene production. The influence of polyethylene prepolymerization
(Brazilian Society of Chemical Engineering, 2000)
The fluidized bed reactor with a prepolymerization system and its influence on polymer physicochemical characteristics
(Brazilian Society of Chemical Engineering, 2003)
Bulk polymerization of styrene in the presence of polybutadiene: effect of initiator type and prepolymerization conditions on particle morphology
(Wiley, 2004-02)
In this study, we investigated the synthesis of high-impact polystyrene through a series of (batch and bulk) polymerizations of styrene in the presence of 6 wt % polybutadiene. The reactions with rubber involved three ...
Bulk prepolymerization of styrene in the presence of polybutadiene: Determination of grafting efficiency by size exclusion chromatography combined with a new extended model
(John Wiley & Sons Inc, 2009-01)
The bulk prepolymerization of styrene in the presence of polybutadiene for the production of highimpact polystyrene is analyzed and compared with an equivalent solution reaction described by Estenoz et al. in 1999. The ...
Linear segmented polyurethanes. II. A mathematical model for the prepolymerization stage
(John Wiley & Sons Inc, 2019-09)
In the first part of this sequel, an experimental investigation on the synthesis of linear segmented polyurethanes was presented,that included estimation of the kinetic constants at 60C for the prepolymerization and finishing ...
Semi-Empirical Quantum Chemistry Method for Pre-Polymerization Rational Design of Ciprofloxacin Imprinted Polymer and Adsorption Studies
(Soc Brasileira Quimica, 2016-01-01)
It is well known that selectivity of molecularly imprinted polymers (MIPs) depends on adequate choice of functional monomer before the experimental synthesis. Computational simulation seems to be an ideal way to produce ...
In vitro evaluation of multi-walled carbon nanotube reinforced nanofibers composites for dental application
(2019-01-01)
The goal of this study was to evaluate the mechanical properties of an experimental composite resin filled with nylon-6 nanofibers (N6), nylon-6 nanofibers with multi-walled carbon nanotubes (N6-MWCN) or with pre-polymerized ...
