Rheo-optical properties of polymers. VI. Dynamic birefringence


  • Paper presented at the Society of Rheology Meeting, Baltimore, Md., October 1962


In previous papers we have presented data on the dynamic birefringence and light scattering from polyethylene. New studies of the dynamic birefringence of polytetrafluoroethylene, silicone rubber, polycarbonate, polymethyl methacrylate, and polyethylene as a function of frequency and temperature have been made. The results are presented and interpreted in terms of various proposed theories. The relationships between the mechanical and optical relaxation spectrum are discussed.
