| Abstract: | The syntheses and characterizations of poly(oxy-trans-1,4-cyclohexyleneoxycarbonyl-1,4-bicyclo2.2.2]octylenecarbonyl) (I) and poly(oxy-trans-1,4-cyclohexyleneoxycarbonyl-1,4-bicyclo2.2.2]octylenecarbonyl-co-oxy-trans-1,4-cyclohexyleneoxysebacoyl) (II) are described. The polymer systems were characterized by infrared spectroscopy, proton magnetic resonance spectroscopy, solution viscosity, and differential scanning calorimetry. The random copolyester prepared from 1:0.65:0.35 mol of trans-1,4-cyclohexanediol, bicyclo2.2.2]octane-1,4-dicarbonyl chloride, and sebacoyl chloride, respectively, formed a birefringent fluid state in the melt. |
