Emulsion Polymerization of MMA employing a Chain Transfer Agent of Low Environmental Impact: Iso-Octyl-3- Mercaptopropionate
(Wiley, 2013-01)
The unseeded batch-emulsion polymerisation of methyl methacrylate (MMA) was investigated using the chain transfer agent iso-octyl-3- mercaptopropionate (iOMP), which exhibits a low environmental impact. The commercial ...
Model polydimethylsiloxanes subjected to thermal weathering: Effect on molecular weight distributions
(Elsevier, 2000-01)
We have subjected samples of model polydimethylsiloxanes of narrow molecular weight distribution to thermo-oxidation in an air circulating oven. Samples remained for up to 1760 h at 200 °C under a standard atmosphere. Loss ...
Modeling of RAFT polymerization using probability generating functions: Detailed prediction of full molecular weight distributions and sensitivity analysis
(Wiley VCH Verlag, 2014-08-06)
A mathematical model of RAFT polymerization processes is presented capable of predicting the full molecular weight distribution (MWD) through the use of probability generating functions (pgf). The bivariate distribution ...
Emulsion Polymerization of Isoprene: Mathematical Model for Long Chain Branching
(John Wiley & Sons Inc, 2011-12)
For a batch emulsion polymerization of isoprene at 10 °C in the presence of a chain transfer agent, a previous mathematical model [Minari et al., J. Appl. Polym. Sci. 2010, 116, 590] was extended for predicting the molecular ...
Mathematical modeling of reverse atom transfer radical polymerization in miniemulsion
(Elsevier, 2018-04-01)
In this work, we study the reverse atom transfer radical polymerization in miniemulsion using a water-soluble initiator. This study is motivated by the technological advantages of performing polymerizations in dispersed ...
Mathematical model for the bulk polymerization of styrene using the symmetrical cyclic trifunctional initiator diethyl ketone triperoxide. I. Chemical initiation by sequential decomposition
(John Wiley & Sons Inc, 2012-03)
In this study, we experimentally and theoretically investigated the use of the symmetrical cyclic trifunctional initiator diethyl ketone triperoxide (DEKTP) in the bulk polymerization of styrene. The experimental study ...
Molecular weight distributions in styrene polymerization with asymmetric bifunctional initiators
(Elsevier, 2004-01)
We model the molecular weight distribution (MWD) of polystyrene obtained using asymmetric bifunctional initiators. We do that by extending an existing model able to predict conversions and average molecular weights. By ...
LDPE Production in Tubular Reactors: Comprehensive Model for the Prediction of the Joint Molecular Weight-Short (Long) Chain Branching Distributions
(American Chemical Society, 2019-03)
Good control on molecular properties, and as a consequence on end-use properties, is very important for low-density polyethylene (LDPE) manufacturers. However, the connection between the architecture of polymer chains and ...
Randomly-Branched Polymers by Size Exclusion Chromatography with Triple Detection: Computer Simulation Study for Estimating Errors in the Distributions of Molar Masses and Branching Degrees
(Wiley, 2013-12)
This article theoretically evaluates the biases introduced into the distributions of molar masses (MMD) and number of long chain branches per molecule (LCBD), when randomly branched polymers are analyzed by size exclusion ...
