Abstract

An automatic rapid elongation system for polymer films is provided in the optical birefringence measurement system using phase modulation technology. It can measure optically and dynamically modular deformation in polymer films during rapid elongation process and stress relaxation after the completion of elongation. Micro and macroscopic information on the deformation in molecules of polymer films can be obtained by measuring birefringence retardation, stress and elastic modulus as the function of time, temperature and percentage of elongation. Advantages, details of the system and some data obtained are described.
