Sentence examples for chain sequence distribution from inspiring English sources
Based on the analysis, the possible chain sequence distribution model for each fraction was proposed.
Polymer chain structural factors, like chain microstructure, comonomer content in copolymer, dyad sequence distribution, molecular weight (MW) and molecular weight distribution (MWD), etc. have a great influence on the properties and applications of polymer materials.
A facile procedure for controlling monomer sequence distribution in radical chain polymerizations.
Their effectiveness during the copolymer synthesis is demonstrated by different techniques and their influence on the final sequence distribution in the chain is discussed.
While random and gradient copolymers of a given overall composition exhibit similar enthalpy recovery values at a common physical aging time and quench depth relative to Tg, the major differences in the enthalpy recovery peaks indicate that differences in sequence distribution along the chain length can lead to unusual behavior in gradient copolymers relative to random copolymers.
The microstructural analysis of the prepared copolymers was performed by 13C (75.5 MHz) nuclear magnetic resonance (NMR) spectroscopy, in terms of sequence distribution and stereochemistry of monomeric units along the copolymer chains.
A better definition is probably the following: Aperiodic copolymers are copolymers in which monomer sequence distribution is not regular but follows the same arrangement in all chains.
Such structures can be defined as copolymers in which monomer sequence distribution is not regular but follows the same arrangement in all chains.
The aromatic 'next to polymer chain' carbon (C7) of donor monomer (1) units is sensitive to the unit 1-centred triad sequence distribution.
Sequence distribution was calculated from 13C{1H}n.m.r.m.r
It was found that most of the VA segments are isolated in the main chain, though three kinds of sequence distributions (VA VA head to tail, VA E VA head to tail, and VA E E VA head to tail) exist in the EVA copolymers with higher VA content.
