## Abstract The synthesis of sideβchain liquidβcrystalline polymethacrylates containing (2__S__)β2βchloroβ4βmethylvaleric acid end groups and 1,2βdiphenylethane based mesogenic units is presented. Differential scanning calorimetry, optical polarizing microscopy and Xβray diffraction were used to de
Aryloxycarbonylphenyl acrylates and methacrylates were prepared by reacting 4-acryloyloxybenzoyl chloride and 4-methacryloyloxybenzoyl chloride with different phenols. They were homopolymerized using benzoyl peroxide as the initiator at 65Β°C in dimethylformamide. The polymers were characterized by I
Liquid crystalline polyetheresters with crown ethers in the mesogenic unit have been synthesized using the DB-[ 181-C-6 crown. This compound was then transferred to the diacetyl-, dicarboxy-and dicarboxydichloride derivatives. After incorporation of the crown ether moiety into the mesogens of main c
