Controlled rheology of polypropylene: Modeling of molecular weight distributions
(John Wiley & Sons Inc, 2003-05)
A mathematical model for the controlled degradation of polypropylene is presented in this article. A previous model of this process was extended to predict the whole molecular weight distribution of the modified resin. ...
Intrinsic Viscosity Determination of High Molecular Weight Biopolymers by Different Plot Methods. Chia Gum Case
(Science and Education, 2018-10)
The chia (Salvia hispanica) generates an abundant and viscous mucilage, this is purified with periods of heating-cooling and finally precipitated with ethanol, obtaining chia gum, CG. In this work the intrinsic viscosity ...
Molecular Weight Distributions in Ideal Polymerization Reactors. An Introductory Review
(Planta Piloto de Ingeniería Química, 2011-10)
The ultimate aim of polymerization reaction engineering is the production of polymers with tailor-made properties. An introductory review into this field is presented, with emphasis on the effects on the molar mass ...
Identification of novel high molecular weight glutenin subunit mutants in bread wheat (Triticum aestivum L.)
(2017-07)
Bread wheat (Triticum aestivum L.) is a staple food crop eaten in different ways like pan and other food products. High molecular weight glutenin subunits (HMW-GS) are major determinants of the different wheat end-use ...
Effect of high molecular weight glutenins and rye translocations on soft wheat flour cookie quality
(2013-11)
The influence of high molecular weight glutenin subunits (HMW-GS) on wheat breadmaking quality has been extensively studied but the effect of different Glu-1 alleles on cookie quality is still poorly understood. This study ...
Modeling and optimization of a high-pressure ethylene polymerization reactor using gPROMS
(Pergamon-Elsevier Science Ltd, 2008-03)
A gPROMS implementation of a comprehensive steady-state model of the high-pressure polymerization of ethylene in a tubular reactor is presented. Model outputs along the reactor length include the complete molecular weight ...
Sclerotium oryzae biocontrol in flooded rice fields with floating microcarrier technology: The effect of chitosan molecular weight
(John Wiley & Sons Ltd, 2021-07)
BACKGROUND: Biocontrol strategies are of significant concern for their application in crops. Various green practices have been designed, but almost all of them had delivery constraints. In particular, to design biocontrol ...
Modeling of the bivariate molecular weight distribution-copolymer composition distribution in RAFT copolymerization using probability generating functions
(Elsevier Science, 2017-08)
In this work, we develop a mathematical model of a RAFT copolymerization process able to predict average molecular properties as well as the full bivariate molecular weight distribution – copolymer composition distribution ...
Catalytic Degradation of Polystyrene: Modeling of Molecular Weight Distribution
(Wiley VCH Verlag, 2011-06)
Two of the most abundant polymers in household waste streams, PS and PE, may be recycled by compatibilization through a Friedel-Crafts alkylation. This reaction produces a graft copolymer PE-g-PS that improves the properties ...
Optimal operation of ethylene polymerization reactors for tailored molecular weight distribution
(John Wiley & Sons Inc, 2007-09-05)
This work presents a comprehensive steady-state model of the high-pressure ethylene polymerization in a tubular reactor able to calculate the complete molecular weight distribution (MWD). For this purpose, the probability ...
