Abstract
A series of copolyesters based on 2-[(S)-(+)-methyl-1-butoxy]hydroquinone, I, as the chiral monomer with non-chiral hydroquinone monomers was investigated for formation of a biphasic morphology in which a cholesteric and isotropic phases coexisted close to an isotropic transition temperature. For the copolyesters with hydroquinone, the biphasic formation occurred for the lower molecular weight copolyester over a wider temperature range presumably because of both molecular weight and the chemical heterogeneity effects on the isotropization transition. The temperature range of the biphasic morphology was influenced by a substituent of the copolymerized non-chiral hydroquinone monomer.
