Abstract

In prior work in this laboratory, measurements of the mechanical and swelling properties of crosslinked natural rubber suggested that the Flory-Higgins interaction parameter Chi is dependent on the crosslink density of the network. Also an analysis of the swelling activity parameter S and the data of Gee, et al for a similar natural rubber suggests a crosslink dependent Chi based on the fact that S in non-zero at the zero swelling. In this paper we present results from isopiestic measurements of solvent uptake by crosslinked and uncrosslinked rubber, calculate S from these measurements and use data at low degree of swelling to argue that Chi is crosslinked dependent.
