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
## Abstract Novel semi‐rigid fluorocarbon‐containing coplycarbonates composed of biphenyl moiety and rigid rod‐like hexafluoropentane chain were prepared by melt polycondensation of 6,6′‐(biphenyl‐4,4′‐diyldioxy)dihexanol (1) and 2,2,3,3,4,4‐hexafluoro‐1,5‐pentanediol (2) with alkylene diphenyl dic
Seven new mesogenic diol monomers CmCn, consisting of two bis(p-oxybenzoyl) units interconnected by a polymethylene segment containing n methylene groups and flanked by two linear w-hydroxyalkyl segments containing m methylene groups were reacted with l$-hexamethylenediisocyanate (HIN) to give a new
