Abstract
The applicability of the coil-strand-transition model to describe the deformation of hard elastic polymers was studied by deformation and re laxation tests of hard elastic polyethylene and hard elastic polypropy lene samples in different liquids. It was found that within the model the calculated values of the fibril diameter,the contribution of surfa ce stress and the total stress are in agreement with measurements. The dominance of energetic contributions to the stress was also confirmed .
