The application of limited swelling in the studies of the cohesive energy density of polyethylene thin film

Abstract

SynopsisThe mechanism and growth of limited swelling of linear high-density polyethylene (LHDPE) in some selected commonly used industrial solvents have been studied. The equilibrium solvent uptake has been used to determine its cohesive energy density. The data obtained during the course of these investigations fits a mechanistic growth model that predicts solvent uptake. This method offers a suitable and alternative way of determining the structural strength and resistance of polymers in contact with common solvents.
