Notes:
A thermodynamic analysis predicts an increase in miscibility, relative to that in the bulk state, for a polymer mixture confined in a capillary with a diameter of the order of the size of the polymer coils. This is derived by using both the concepts of growing domains and a consideration of the thickness of polymer-polymer interfaces. The analysis is combined with a Monte Carlo lattice simulation that provides results on such confined systems. Intermixing, described in terms of the number of heterocontacts and the dimensions of the polymer chains in the capillary parallel and perpendicular to the tubular axis, is investigated. The results confirm that demixing in homogeneous mixtures is hindered, whereas intermixing is enhanced, in the capillary relative to that in the unconfined mixture. © 1992 John Wiley & Sons, Inc.
