New polyarylene ethers containing rigid naphthalene, pyridine and quinoline moieties have been prepared by the nucleophilic displacement of suitable aromatic dihalides with corresponding potassium bisphenates. The reaction was carried out using DMAc or DPS as solvent. The chemistry and thermal prope
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
New polyesters containing both silane and ''cardo'' groups were synthesized by solution polycondensation involving the reaction of bis(4-chlorocarbonylphenyl)dimethylsilane with cardo bisphenols, namely, phenolphthalein, phenolphthalimidine, and phenolphthalein anilide. Copolyesters were obtained by
