Statistical Mechanics of Polymer Melting Transition

Journal of the Physical Society of Japan, 1988
The Flory-Huggins model without solvent molecules on a brick lattice is solved exactly by the Bethe ansatz. It is shown that polymer melting given by this model is a second order transition which verifies the conjecture of Gujrati and Goldstein. It is also found that the gauche fraction turns out to be zero in the low-temperature phase.

Statistical mechanics of inhomogeneous model colloid—polymer mixtures

Molecular Physics, 2003
We describe two strategies for tackling the equilibrium statistical mechanics of inhomogeneous colloid—polymer mixtures treated in terms of the simple Asakura—Oosawa—Vrij (AO) model, in which colloid—colloid and colloid—polymer interactions are hard-sphere like, whereas the polymer—polymer interaction is zero (perfectly interpenetrating polymer spheres)

Statistical mechanics of temporary polymer networks I. The equilibrium theory

Rheologica Acta, 1984
This work treats the equilibrium state of temporary polymer networks in which the junctions are allowed to decay and to form. The network is described as an open system and a modified spring-bead model is assumed. The decaying and reforming beads bring about the viscous behaviour in addition to the elastic behaviour of the permanent network.

The statistical mechanics of a melt of polymer rings

Journal of Physics A: Mathematical and General, 1995
Topological restrictions are introduced into a melt of flexible polymer rings by specifying the linking number between each pair of rings. Attention is focused on the configurational properties of a single ring in the melt, where the winding number between each pair of rings is zero.

Statistical mechanics of polymers with distance constraints

The Journal of Chemical Physics, 1994
The ensemble of polymer conformations satisfying some distance constraints is studied using the replica approach. Dependence of the number of such conformations on the number of constraints is obtained. Possible implications of these results for the physics of polymer gels and the problem of protein structure reconstruction from NMR are discussed.

Statistical Mechanics of Dilute Polymer Solutions. II

The Journal of Chemical Physics, 1950
New thermodynamic relationships applicable to dilute solutions of heterogeneous high polymers are derived. The function previously given to express the interaction between two polymer molecules of equal size is modified to include chemically similar polymer molecules differing in size.

General formulation of the statistical mechanics of multicomponent polymer systems

Acta Polymerica, 1994
AbstractThis paper summarizes different approaches to strongly interacting polymer systems. The first part of the paper discusses repulsive systems, i.e. polymers in a good solvent, polymer melts and blends. Corresponding field theories are reviewed and critically revisited from different points of view.

Statistical Mechanics of Polymer Networks

1992
By using the scaling theory for the total number of configurations of general polymer networks, the critical exponents associated with the short distance behavior of the end(A)-to-end(B)distance(r AB ) Distribution function gG(r AB )~>(r AB )θGof a polymer network G is obtained as θG=[γ(n A)+γ(n B)−γ(n A+n B)−1]/v, Where n A(or n B)denotes the number ...

Statistical Mechanics of Directed Polymers

1995
Much effort has been expended in this century towards understanding correlations and dynamics of dense liquids of pointlike atoms and molecules [1]. Particularly noteworthy is the pioneering work by Ornstein and Zernike [2], who argued that the density fluctuations are Gaussian and determined the form of the static correlation functions at long ...
