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 …
