Ay. Bilibin et al., SYNTHESIS OF SEVERAL SERIES OF LIQUID-CRYSTALLINE POLYAROYL-BIS-OXYARYLATES AND THEIR STRUCTURE-PROPERTY RELATIONSHIPS, Liquid crystals, 14(6), 1993, pp. 1661-1666
Several series of liquid crystalline polyaroyl-bis-oxyarylates contain
ing 1,4-phenylene, 4,4'-biphenylene and 2,6-naphthylene units have bee
n synthesized with the use of aroyl-bis-oxyaroyl dichlorides. Melting
and clearing temperatures of every polymer under investigation were co
mpared with those of corresponding polyterephthaloyl-bis-4-oxybenzoate
