Studies are conducted on the dynamics and relaxation behavior of glassy         polymers.  Experimentally, the methods of modern high-resolution NMR of         solids will be used in conjunction with a recently developed                    dilatometry technique as a probe of the molecular motions and                   chain-packing effects in glassy polymers.  In particular, the                   investigator will perform so-called CPMAS NMR experiments on                    polycarbonates under high carbon dioxide pressure to obtain information         on the effects of absorbed gas molecules on the molecular motions and           chain packing.  The investigator will also use multiple quantum NMR to          obtain new information about the extent of correlated motion of the             polymer in the glass and to correlate the NMR experiments with                  macroscopic properties, e.g. dynamic mechanical loss.  Theoretically,           the investigator will use a combination of computer simulations,                phenomenological model building, and statistical mechanics to                   understand the relaxation processes in glassy polymers.
