Thermotropic polyamides with high molecular weights were synthesized by melt polycondensation of 3,3'-disubstituted-4,4'-biphenylenediacetamides with a,o-diphenoxyalkane-4,4'dicarboxylic acids. Methyl, methoxy, and chloro groups were used as 3,3'-substituents. IR measurements revealed that there are

A series of thermotropic liquid crystalline polyesters based on p-hydroxybenzoic acid, terephthalic: acid, 2,6-dihydroxynaphthalene and containing small amounts of either Bisphenol A, 2,7-dihydroxynaphthalene, or polyethylene terephthalate (PET) as comonomers were prepared. The latter three material
## Abstract Two series of fluorineβcontaining liquid crystalline polyesters were synthesized from fluorinated alkylene diols and mesogenic acid dichlorides. The thermal behaviour of the polymers differs considerably from that of their hydrocarbon analogues. Formation of a nematic phase was observed
Thermotropic liquid-crystalline polyquinolines with high molecular weights, i.e., poly[2,2 -(a,v-dioxyphenylene (or -dioxybiphenylene) alkane)-6,6 -(4,4dioxybiphenyl)-bis(4-phenylquinoline)]s (P-H-B1Mns or P-H-B2Mns), were synthesized by polycondensation of 4,4 -bis(4-amino-3-benzoylphenoxy)biphenyl
We have determined the surface energies (β₯ s ) of two liquid crystalline polyesters (Vectraβ’ A-950 [Hoechst Celanese, NJ] and Xydarβ’ [Amoco, GA]) and one polyesteramide (Vectraβ’ B-950 [Hoechst Celanese, NJ]) using contact angle techniques at room temperature. These LCPs were dissolved in bis-trifluo
