Statistical Mechanics of High Polymer Solutions

Australian Journal of Chemistry, 1948
The configurational partition function for random mixtures containing any numbers of components which can consist of simple, simple chain, branched chain, or closed ring molecules is examined. Using a general statistical method a set of partial differential equations is obtained for the appropriate combinatory factor.

Statistical Mechanics of Sterically Interacting Ring Polymers

Journal of the Physical Society of Japan, 1984
This paper derives a new model describing sterically interacting polymers in a solution, a finite fraction of which forms closed rings. The model is closely related to a magnetic partition function for classical spin model, but vanishing limit ( n →0) for the internal degrees of freedom is not assumed. For given average molecular weights and amounts of

Statistical Mechanics of Flexible High Polymers at Surfaces

The Journal of Chemical Physics, 1957
The isotherm corresponding to monolayer adsorption and the equation of state of a monolayer at a liquid interface are derived. As previously, we replace the number of segments per chain actually deposited, by an average value, which is proportional to t½ (t total number of segments) and depends on chain flexibility.

Statistical boundary value problems of polymer mechanics

Polymer Mechanics, 1972
Research on statistical boundary value problems with applications in the mechanics of reinforced polymers is briefly reviewed. The common features of the models and mathematical methods used in connection with polycrystalline metals and materials of the glass-reinforced plastic type are noted.

Statistical mechanics of polymer networks of any topology

Journal of Statistical Physics, 1989
The statistical mechanics is considered of any polymer network with a prescribed topology, in dimensiond, which was introduced previously. The basic direct renormalization theory of the associated continuum model is established. It has a very simple multiplicative structure in terms of the partition functions of the star polymers constituting the ...

Statistical Mechanics of End-Attached Polymer Interfaces

1998
This dissertation discusses several closely related problems involving end attached polymers at interfaces. The studies share a numerical self-consistent field approach which is described in detail in Chapter 1. In Chapter 2, we consider irreversible polymer brushes (polymers densely end tethered to a surface). First, we discuss the adequacy of second

Statistical mechanics of localized states in conducting polymers

Synthetic Metals, 1987
Abstract We derive the thermodynamics of the electrochemical doping of a polymer chain with localized charged states, taking into account the effects of size and mutual interactions. The possible compressibility of the states gives rise to an overdoping with an apparent capacitance-like relation between charge and potential. Then we study the case of

Irreversible Statistical Mechanics of Polymer Chains. II. Viscosity

The Journal of Chemical Physics, 1971
The Fokker–Planck diffusion equation derived in the previous paper is applied to Erpenbeck–Kirkwood theory on the viscosity of polymer solutions. The Newtonian viscosity for ring polymers is given by ηN = 2ckT ∑ σ = 1N τσ / (1 + iωτσ), where τσ is the relaxation time, c is the number of polymers in unit volume, and kT has the usual meaning.
