Abstract

In this work, the authors reanalyze the gel-solvent relationship by examining the freezing and melting point depression of solvent in crosslinked natural rubber (NR). They present new calorimetric data on both the freezing and melting of solvent crystals in crosslinked and uncrosslinked natural rubber swollen to various degrees in benzene. The data are used to illustrate the methodology used by Flory to describe melting-point depression in these systems. As alluded to earlier, the application of the Flory calculation to solvent freezing, where nucleation is a concern, rather than to solvent melting, is a source of misunderstanding in prior studies of the rubber/benzene system.
