The magnitude of both components seems to depend mainly on the mean hydrophobicity of the monomer and not on the polymer molecular weight or dispersity. eng info:eu-repo/semantics/openAccess http://creativecommons.org/licenses/by-nc-nd/4.0/ Attribution-NonCommercial-NoDerivatives 4.0 Internacional Endothermic and exothermic components of an inverse temperature transition for hydrophobic association by TMDSC info:eu-repo/semantics/article
