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 predominatly confined between the smectic layers, I find that the presence of the polymers can lead to a re-entrant 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 re-entrant phase boundary.
