Book excerpt: This project concerned the fundamental understanding of processing-structure and structure-property relations in block copolymer and liquid crystalline polymer systems. Key to our studies was the availability of model materials which afforded opportunities via new chemical compositions and physical properties. Transmission electron microscopy, low voltage high resolution scanning electron microscopy, light microscopy and atomic force microscopy as well as wide and small angle x-ray scattering were the principal characterization tools. We also employed a special roll cast process to form highly textured samples for investigation of their physical properties. Principal research accomplishments are grouped into 6 areas: influence of architecture on phase behavior; development of experimental techniques; microphase separation in block copolymers; large strain deformation of single crystal thermoplastic elastomers; morphology and dynamic interaction of defects in polymer liquid crystals; and technology transitions.
