Abstract
The biphasic behavior was studied for two polyacrylates 1 and 2, by DS C by annealing the polymers inside the respective apparent biphasic ga p associated with the nematic-isotropic transition (polymer 1) or to t he smectic Ad-isotropic transition (polymer 2). A biphasic thermal ran ge in which isotropic and smectic Ad phases or isotropic and nematic p hases coexist at equilibrium was revealed. In both cases, the thermody namic width of the biphasic region was estimated to be about 2.0 K.
