Abstract
The measurements of dynamic optical birefringence is described, togeth er with instrumentation for this purpose. Complex birefringence, stres s- and strain-optical coefficients are determined simultaneously with complex mechanical properties (E' and tan delta(m)). Results are shown for poly(vinyl chloride) comparing data obtained in this study with e arlier measurements. Optical birefringence is shown to be a very sensi tive probe for molecular motions and is therefore a useful structural elucidation tool.
