Abstract

We report a theoretical study of the equilibrium statistical mechanics of polymer chains end-grafted in the dense liquid state to a surface. We consider the special features which arise when two immiscible polymer species are present. In constrast to ungrafted polymer blends, this system has two distinct scaling regimes of strong immiscibility: endsegregated and fully segregated. We discuss the mixing energy and bistability properties in each regime using approximations valid for large chain elongation.

25. In general one might expect the interaction parameter A to depend on the local state of chain elongation. However, since the local distortion induced by the elongation of our chains is arbitrarily weak, the elongation being arbitrarily smaller than full extension, we expect such effects to be unimportant. Thus it should be safe to simply add the two contributions to the local effective pressure.Google Scholar
