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. ...
ANTIFUNGAL ACTIVITY AND RELEASE OF COMPOUNDS ON RHIZOPUS STOLONIFER (EHRENB.:FR.) VUILL. BY EFFECT OF CHITOSAN WITH DIFFERENT MOLECULAR WEIGHTS.
(2013-03-05)
The effect of chitosan on mycelial growth, protein release, glucose consumption, hexokinase activity and the release of compounds was studied in three isolates of Rhizopus stolonifer. The chitosan of low, medium and high ...
An approach for complete molecular weight distribution calculation: application in ethylene coordination polymerization
(2008)
The objective of this article is to present an approach to ascertain the molecular weight distribution (MWD) of polymeric systems and its application to an industrial polyethylene reactor. Ascertaining the complete MWD can ...
Control of Molecular Weight Distribution in Emulsion Polymerization Using On-Line Reaction Calorimetry
(American Chemical Society, 2001-01)
The molecular weight distribution (MWD) of linear polymers was controlled based on on-line reaction calorimetry. A method to estimate the MWD from reaction calorimetry when chain transfer to a chain-transfer agent is the ...
Prediction of the full molecular weight distribution in RAFT polymerization using probability generating functions
(Elsevier, 2014-07)
In this work, a model for the RAFT polymerization following the slow fragmentation approach was developed in order to obtain the full molecular weight distribution (MWD) using probability generating functions (pgf). A ...
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 ...
SAXSMoW 3.0: New advances in the determination of the molecular weight of proteins in dilute solutions from SAXS intensity data on a relative scale
(2022-01-01)
SAXSMoW (SAXS Molecular Weight) is an online platform widely used over the past few years for determination of molecular weights of proteins in dilute solutions. The scattering intensity retrieved from small-angle X-ray ...
