Modelling polymers with side chains: MEH-PPV and P3HT
(2013-04-01)
Modelling polymers with side chains is always a challenge once the degrees of freedom are very high. In this study, we present a successful methodology to model poly[2-methoxy-5-(2′-ethyl-hexyloxy)-p-phenylenevinylene] ...

Shear damping function measurements for branched polymers
(John Wiley & Sons Inc, 2007-12)
We present results for step-strain experiments and the resulting damping functions of polyethylene blends of different structures, including solutions of linear, star and comb polymers. Remarkably, an entangled melt of ...
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 ...
Star polymers rupture induced by constant forces
(American Institute of Physics, 2014-10)
In this work, we study the breakage process of an unknotted three-arm star-shaped polymer when it is pulled from its free ends by a constant force. The star polymer configuration is described through an array of monomers ...
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 ...
Modeling of the Nitroxide-Mediated Radical Copolymerization of Styrene and Divinylbenzene
(Wiley-v C H Verlag GmbhWeinheimAlemanha, 2009)
Emulsion Copolymerization of Acrylonitrile and Butadiene in an Industrial Reactor. Mathematical Modelling, Estimation, and Control of Polymer Quality Variables on the Basis of Calorimetric Measurements
(Planta Piloto de Ingeniería Química, 2003-05)
An industrial emulsion copolymerization of acrylonitrile and butadiene carried out in a batch (or semibatch) reactor for the production of nitrile rubber (NBR) is investigated. The effect of variable amounts of deactivating ...
