  We formulate the dynamical theory of nematic polymers, starting from a
microscopic Poisson bracket approach. We find that the Poisson bracket between
the nematic director and momentum depends on the (Maier-Saupe) order parameter
of the nematic phase. We use this to derive reactive couplings of the nematic
director to the strain rates. Additionally, we find that local dynamics breaks
down as the polymers begin to overlap. We offer a physical picture for both
results.
