The study shows that the addition of side spheres results in key modifications of standard polymer behavior, leading to a marginally compact phase with reduced dimensionality and ordered structures at low temperatures. The model polymer chain serves to partially bridge conventional polymer phases with biomolecular phases.
We present the results of a quantitative study of the phase behavior of a model polymer chain with side spheres using two independent computer simulation techniques. We find that the mere addition of side spheres results in key modifications of standard polymer behavior. One obtains a marginally compact phase at low temperatures; the structures in this phase are reduced in dimensionality and are ordered, they include strands assembled into sheets and a variety of helices, and at least one of the transitions on lowering the temperature to access these ordered states is found to be first order. Our model serves to partially bridge conventional polymer phases with biomolecular phases.
