Bimodal distribution in branched polymer solutions
نویسنده
چکیده
2014 We study the swelling of one very large molecule made of N monomers in a mixture of a good solvent and shorter polymers of P units of the same chemical species. All the macromolecules are branched. The total concentration is larger than the contact concentration C* of the short chains. When P decreases, the radius of gyration of the probe chain crosses-over from a N 1/3 behaviour typical of concentrated solutions to a N 1/2 law characteristic of dilute solutions. The cross-over occurs around a value P* ~ N5/6. The monomer correlation functions are also studied. J. Physique 43 (1982) 1781-1787 DTCEMBRE 1982, 1 Classification Physics Abstracts 05.20 61.40

Conformations of polydisperse polymer solutions : bimodal distribution
2014 Starting with the Flory theory for one long flexible polymer chain of N segments in a homopolymer melt of shorter (P segments) chains, we employ scaling arguments to construct the « phase diagram » of an athermal bimodal solution, i.e. a ternary system composed of N chains, P chains, and solvent. Qualitatively the presence of short chains reduces the effective solvent quality as experience...
متن کاملThermodynamjc Interactions in Dilute Polymer Solutions: the Virial Coefficients
The statistical thermodynamics of dilute polymer solutions is reviewed from the point of view of the continuum theory based on molecular distribution functions. The comparatively rigorous perturbation treatment of the second and third virial coefficients, and various approximate theories derived from it to give closed-form expressions useful for good-solvent systems. are outlined. Indications f...
متن کاملPrediction of the soil-water characteristic curve of dune sand stabilized with SBR polymer and MICP process in the Jabal Kandi area
Introduction The geotechnical engineering problems involving unsaturated soils are included water flow, shear strength and volume change. Soil-water characteristic curve (SWCC) describes the constitutive relationship between soil suction and soil water content. SWCC may be determined directly or indirectly in the laboratory. Because of the various difficulties involved in the direct measuremen...
متن کاملEffect of Chain Transfer to Polymer in Conventional and Living Emulsion Polymerization Process
Emulsion polymerization process provides a unique polymerization locus that has a confined tiny space with a higher polymer concentration, compared with the corresponding bulk polymerization, especially for the ab initio emulsion polymerization. Assuming the ideal polymerization kinetics and a constant polymer/monomer ratio, the effect of such a unique reaction environment is explored for both ...
متن کاملEstimation of the Molecular Weight Distribution of Linear Homopolymer Blends from Linear Viscoelasticity for Bimodal and High Polydisperse Samples
This work is concerned with the approximate solution of the problem generated by the integral of first kind relating the shear relaxation modulus of entangled, linear and flexible homopolymer blends and the molecular weight distribution (MWD). Procedures are proposed to estimate the density distribution function (DDF) of the MWD from numerical solutions of the theoretical model composed by the ...
