    • For semidilute and dense solutions, we only studied fully flexible chains swollen in an athermal (vacuum) solvent. Each solution consists of M = 50 chains of length N = 1000. The conformations were provided by B. Dünweg and P. Ahlrichs (32).

    • pp relative to the ideal case of infinitely thin entangled lines. The present algorithm disregards intrachain entanglements. As studies on ring polymers show, they are only of minor relevance. We are currently working on a variant of the algorithm that overcomes these limitations.
