摘要：

In this paper we propose a model for coal swelling based on a process called disinterspersion. This allows a calculation of the “molecular weight” or number of aromatic “clusters” between cross-link points under the assumption that rigid chains swell with little or no change in average conformation up to a limit imposed by the geometry of the network. Sample calculations are presented and suggest that for an Illinois No. 6 coal the “molecular weight” between cross-link points is small. © 1990, American Chemical Society. All rights reserved.
