CONFORMATIONAL-CHANGES AND PHYSICAL AGING IN BISPHENOL-A POLYCARBONATE - ORIGINS OF MECHANICAL-PROPERTIES Conference Paper uri icon

abstract

  • An understanding of structure/property relationship is essential for efficient development of new materials. The aging process yields significant changes in the physical and mechanical properties associated with a polymer such as embrittlement, decrease in yield strength and stress relaxation behavior. Techniques as nuclear magnetic resonance, infrared spectroscopy electron microscopy and molecular modeling are employed to determine the polymeric structure before and after the aging process. This study correlates the changes in conformational structure, determined through X ray diffraction and Raman spectroscopy with the aging mechanism. The ultimate goal will be to develop a model that may be applied to other high thermoplastics.
