Abstract
Abstract: In this study, we propose the dispersive (“long-tail) kinetics concept as a possible candidate for elucidating qualitatively some experimentally noticed departures from the constancy in a polymer crystal growth rate against time behavior. It turns out to be a consequence of some more detailed consideration of the polymer (colloid) mass-dependent diffusion coefficient, which is consistent with a microscopic picture of the entire crystallization phenomenon, that is basically a nucleation-and-growth process. The phenomenon under consideration appears to be solution controlled, with a dominant role of solute or solute-solvent interactions. The random adsorption of macromolecules cannot drastically change this picture.
