摘要：
The biphasic behavior was studied for two polyacrylates 1 and 2, by DSC by annealing the polymers inside the respective apparent biphasic gap associated with the nematic-isotropic transition (polymer 1) or to the smectic Ad-isotropic transition (polymer 2). A biphasic thermal range in which isotropic and smectic Ad phases or isotropic and nematic phases coexist at equilibrium was revealed. In both cases, the thermodynamic width of the biphasic region was estimated to be about 2.0 K.
