  I consider the effects of polymers on the smectic phase of a host liquid
crystal matrix. Focusing on the regime in which the polymers are predominately
confined between the smectic layers, I find that the presence of the polymers
can lead to a reentrant phase diagram with the smectic-C sandwiching the
smectic-A phase from both the high and low temperature sides. Simple
entropy-energy arguments predict the shape of the reentrant phase boundary.
