    A general model for the description of the stress-strain behavior of polymer networks is introduced. We assume that the network consists of a gas of phantom chains. Its deformation is accounted for by macroscopic constraints, which allow nonaffine behavior on the microscopic scale. The advantage...

    We study the macroscopic behavior of homopolymers and block copolymers at the interface of two different phases focusing on the random walk nature of the polymer chains. The macromolecules or parts of them can belong to either one of the phases and are described by a simple model of random walks...
