Notes:
Thermotropic liquid-crystalline poly(1,4-phenylene terephthalate)s with phenylalkyl side chains were synthesized. The influence of this novel type of substituent on the thermal properties and solubility behavior is discussed. In common solvents soluble, liquid-crystalline polyesters with low transition temperatures were obtained when the phenylalkyl substituent was introduced in combination with a bulky substituent or when both phenyl rings were substituted with phenylalkyl side chains. When poly(1,4-phenylene terephthalate) is only monosubstituted with a phenylalkyl substituent in the 1,4-phenylene unit, the polyesters have melting temperatures above 310°C and are only soluble in solvents such as p-chlorophenol.
