Estimation of the Unperturbed Chain Dimensions of Poly(Vinyl Chloride) Polymer by Various Methods
Flory Fox, Kurata-Stockmayer, Berry, Inagaki-Suzuki-Kurata, Stockmayer-Fixman and Ahmad-Baloch methods based on the excluded volume theory have been applied to poly(vinyl chloride)-cyclohexanone system to obtain Kq and the radius of gyration. A discussion on the reliability of these methods is given. The Stockmayer-Fixman and Ahmad-Baloch methods are found to be...
متن کاملContributions of short-range and excluded-volume interactions to unperturbed polymer chain dimensions.
A Monte Carlo study is made of the mean-square radius of gyration for the freely rotating chain with such fictitious excluded-volume interactions that the Lennard-Jones 6-12 potentials at the Theta temperature act only between the fourth-through (3+Delta)th-neighbor beads (Delta > or = 1) along the chain. The behavior of the asymptotic value (/n)infinity of the ratio /n as a functi...

متن کاملStiffness of polymer chains
A formula is derived for stiffness of a polymer chain in terms of the distribution function of end-to-end vectors. This relationship is applied to calculate the stiffness of Gaussian chains (neutral and carrying electric charges at the ends), chains modeled as self-avoiding random walks, as well as semi-flexible (worm-like and Dirac) chains. The effects of persistence length and Bjerrum’s lengt...
متن کاملDeciphering Functions of Branched Ubiquitin Chains
The anaphase-promoting complex/cyclosome targets proteins for degradation by catalyzing homotypic ubiquitin chains of different linkage types. In this issue of Cell, Meyer and Rape diversify the degradation signals by demonstrating that the APC/C and its cognate E2 conjugating enzymes enhance the rate of substrate degradation by decorating them with branched Lys11 and Lys48 ubiquitin chains.
