De Los Rios, Paolo and Caldarelli, Guido Cold and warm swelling of hydrophobic polymers. Physical Review E, 63 (3). ISSN 1539-3755 (2001)Full text not available from this repository.
We introduce a polymer model where the transition from swollen to compact configurations is due to interactions between the monomers and the solvent. These interactions are the origin of the effective attractive interactions between hydrophobic amino acids in proteins. We find that in the low and high temperature phases polymers are swollen, and there is an intermediate phase where the most favorable configurations are compact. We argue that such a model captures in a single framework both the cold and the warm denaturation experimentally detected for thermosensitive polymers and for proteins.
