Pulsed dynamic NMR of fibers from thermotropic liquid-crystal polymers

Semiflexible liquid--crystal polyesters were melt spun into highly oriented fibers with tensile moduli up to E = 22 GPa and studied by pulsed dynamic NMR techniques. Analysis of the various exp 2 H NMR experiments provided detailed information about molecular order and dynamics of these systems. As-...
