Abstract
The morphology development in a PS/LLDPE 95/5 blend after uniaxial elongation at constant stress is investigated with a special attention on the influence of the temperature on the competition between shape recovery and droplet breakup. The lower the recovery temperature, the finer the morphology obtained, i.e. fibril breakup was preferred against shape recovery. This is due to a stronger retraction of matrix molecules at higher temperatures in early stages of recovery which forces the fibrils to shrink back to less deformed states and thus suppresses the droplet breakup. The elasticity of the blend was found to increase with temperature although the elasticity of pure PS is temperature independent. This is explained as a consequence of the temperature dependence of the morphology development.
