Progress in the Free and Controlled Radical Homo- and Co-Polymerization of Itaconic Acid Derivatives: Toward Functional Polymers with Controlled Molar Mass Distribution and Architecture. [PDF]

open access: hybridMacromolecular rapid communications, 2020
Polymeric derivatives of itaconic acid are becoming increasingly more interesting for research and industry because itaconic acid is accessible from renewable resources.

Evolution of Molar Mass Distributions Using a Method of Partial Moments: Initiation of RAFT Polymerization [PDF]

open access: goldPolymers, 2022
We describe a method of partial moments devised for accurate simulation of the time/conversion evolution of polymer composition and molar mass.

Molar-mass distribution of urea–formaldehyde resins of different degrees of polymerisation by MALDI-TOF mass spectrometry [PDF]

open access: greenJournal of the Serbian Chemical Society, 2010
This paper describes some results obtained in an investigation of urea–formaldehyde (UF) resins of different degrees of polymerisation by matrix-assisted laser desorption/ionisation time-of-flight (MALDI-TOF) mass spectrometry (MS).

Solvent-Free Solid-State-Processed Tapes of Ultrahigh-Molecular-Weight Polyethylene: Influence of Molar Mass and Molar Mass Distribution on the Tensile Properties

open access: green, 2015
In normal practice, ease in processing comes at the expense of a reduction in mechanical properties. Here we show that by controlled synthesis it is possible to synthesize a wide range of linear ultrahigh-molecular-weight polyethylenes that can be ...

Randomly‐Branched Polymers by Size Exclusion Chromatography with Triple Detection: Computer Simulation Study for Estimating Errors in the Distribution of Molar Mass and Branching Degree [PDF]

open access: bronze, 2014
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 chromatography (SEC) with molar ...

Molar mass estimate of dark matter from the dark mass distribution measurements [PDF]

open access: greenPhysical Review D, 2003
We study the distribution of dark matter versus visible matter using a set of data obtained from strong gravitational lensing in the galaxy cluster CL0024+1654 and another set of data inferred from the universal rotation curves in spiral galaxies. The important feature of these two dramatically different observations is that the mass density profile of
