The approach to polymer morphology dynamics developed in our previous paper (Physica 143A (1987) 349) is applied to block copolymer systems. The combination of the reptation idea and the incompressibility requirement introduces correlations among reptative motions, where polymer ends as well as...

A general kinetic equation of the monomer density variables for polymer blends and block copolymer melts is obtained which describes slow morphology variations. The general theory is applied to a polymer blend adopting the biased reptation model of a polymer chain under mean field. We obtain an...

Polymer gel serves as a model system which represents many aspects of static and dynamic processes in solids in an amplified manner both spatially and temporaly. We will give a brief overview of those aspects and refer to the recent topics on the subjects.

We generalize the model of the nucleation-and-growth process studied by Kolmogorov, Johnson, Mehl and Avrami. We then derive the exact space-time correlation functions of the two-phase structure which consist of metastable phase and stable phase. The result includes the case in which the...

We continue to study the size distribution of domains in a 1-dimensional anisotropic ferromagnetic system in the presence of magnetization switching. We construct the evolution equation of the size distribution function of switched domains by using the results of the previous paper. Long time...

Two-dimensional crystal growth in a three-dimensional diffusion field of super-saturated vapor is studied theoretically. Both surface kinetics and diffusion are taken into account near the growing edge of the crystal. A conformal mapping technique is employed for solving the diffusion field near...

A saddle-point configuration of the symmetric ø4-model is obtained in (2+0)-dimensions under a boundary condition such that the solution øs(x,y) represents the domain walls along x- and y-axes far from the origin. We performed a linear stability analysis of the solution øs(x,y) numerically,...

We construct the evolution equation of the size distribution function of the unswitched domains of a model of a 1-D system in a switching field, and solve it as an initial value problem. As the time goes on, the distribution approaches to the “fixed point”, which is the exponential...

A new viewpoint on the kinetics of Ostwald ripening is presented by studying the kinetic equation recently derived for the late stage of phase separation. It is shown that the average droplet radius grows as t13 and the number density of droplets decays as t-1. An important effect of a soft...

The effect of crystal orientation of grains on grain growth is investigated by computer simulation. A vertex model which includes the orietation dependence of grain boundary energy is used. It is shown that the orientation effect gives rise to more distortion and more diversity in the shape of...
