Polydimethylsiloxanes of narrow molecular-weight                           distribution and with primary and secondary amine end groups will               be prepared by initiating the anionic polymerization of the                     cyclic trimer, hexamethylcyclotrisiloxane, with lithium bases                   containing protected nitrogen.  After polymerization, the                       protecting group will be removed and the amino-ended silicones                  will be converted to block copolymers.  Such copolymers will be                 composed of rubbery silicone segments and polar, rigid segments                 which should undergo microphase separation.  Silicone-                          polyurethane and silicone-polyurea block copolymers will be                     prepared.  These will be examined by small-angle x-ray                          scattering, thermal-mechanical analysis, and dynamic-mechanical                 analysis.  Fundamental relationships between molecular weight of                silicone or hard segment and separated domain size and thermal-                 mechanical properties will be derived.                                               This research project is part of the NSF effort to enhance                 support for undergraduate research.
