Abstract
The syntheses and characterizations of poiy[oxy(2-chloro-l,4-phenylene)oxycarbonyl- l,4-bicyclo[2.2.2] octylenecarbonyl-co-oxy(2-chloro-l,4-phenylene)oxysebacoyl] and poly[oxy(2-methyl-l,4-phenylene)oxycarbonyl-l,4-bicyclo[2.2.2]octylenecarbonyl-co-oxy(2-methyl-l,4-phenylene)oxysebacoyl] are described. The resulting random copolyesters were characterized by infrared spectroscopy, proton magnetic resonance spectroscopy, solution viscosity, and differential scanning calorimetry. The random copolyesters formed birefringent fluid states in the melt.
