Abstract
The mechanical properties of polymeric materials are of considerable importance to their engineering applications, and the increased need for more detailed data and a better understanding of the mechanisms involved in polymer deformation has led to the search for new experimental techniques to characterize transient structural changes during mechanical processes. Simultaneous vibrational (FTIR) spectroscopic and mechanical (so-called rheo- optical) measurements have emerged as a very informative probe for the study of deformation and relaxation phenomena in polymer films in the late seventies and have since then been applied to obtain data on the orientational and conformational changes and strain-induced crystallization during the mechanical treatment of a wide variety of polymers.© (1992) COPYRIGHT SPIE--The International Society for Optical Engineering.
