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 کاملGas Selective Properties of Poly(4-Methyl-1-Pentene) Modifed by Gas Phase Fluorination
Fluorine-containing polymers have a number of valuable physical and chemical properties, such as high chemical and heat resistance, high mechanical strength and highly selective gas separation characteristics. One of the ways to produce fluoropolymer membranes is through surface fluorination. The modifcation of commercial polymers with membrane properties, poly(4-methyl-1...
متن کاملPressure-induced structural change of intermediate-range order in poly(4-methyl-1-pentene) melt.
High-pressure in situ x-ray diffraction and specific-volume measurements on isotactic poly(4-methyl-1-pentene) melt have uncovered abrupt changes in the pressure dependence of microscopic structure as well as that of macroscopic density. The first sharp diffraction peak of the polymer melt, which is related to the intermediate-range order and is explained as resulting from the correlations betw...
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...
