DURIP Advanced Polymer Solid State NMR Instrumentation

Abstract

The grant provided instrumentation which has been included within our Laboratory for the advanced Nuclear Magnetic Resonance study of polymers in the solid state. The substantial majority of our initial, specific NMR objectives have been accomplished. These include the study of the structure and morphology of Poly(p-phenylene vinylene) (PPV) and the Molecular Interactions in High Temperature Polymer Blends. The instrumentation has provided experimental capability in two new areas which are being used generally in further work. In particular we have 1) implemented methods for the NMR study of the structure and orientation of high strength films and fibers. These methods are now being used for the study of PBZT fibers, 2) Two-dimensional NMR methods have been developed which provides for quantitative measurement of conformation and domain structure of blends. Two-dimensional NMR will be a major thrust of future NMR blends experiments.
