All of poly(2c), poly(3), and poly(4a) completely dissolve in many organic solvents such as aromatic hydrocarbons (e.g., toluene), halogenated hydrocarbons (e.g., CHCI3), and tetrahydrofuran (Table VI). Furthermore, poly(2c) and poly(4a), which are aliphatic polymers, are also soluble in aliphatic hydrocarbons (e.g., hexane). On the other hand, poly(3), which is an... 

The poly(phenylacetylene) (poly-PA) formed is from dark red to orange with a molecular weight of from 5 to 50 thousand. The polymers are air-stable and totally soluble in aromatic and halogenated hydrocarbons. The poly-PA has a mainly trans configuration of the olefinic protons, as was determined by IR and H-NMR spectroscopies [20]. In the residue obtained after the separation of poly-PA oligomerisation products we also detected a dimer of phenylacetylene, diphenylbutadiene and cyclotrimers, and different positional isomers of... 

The preparation of wholly aromatic sterns in halogenated hydrocarbon-salt mixtures, poly(l,4-benzamide) synthesis by thermal and suspension methods and extended chain systems, and their liquid crystal solutions have similarly been reviewed. The polycondensation of poIy(p-benzamide) chain ends has been shown to occur in the solid and liquid-crystalline state and the reactivity in the former exceeds that in the latter. Poly(l,4-phenyleneterephthalamide) and poly(chloro-l, 4-phenyleneterephthalamide) have been synthesized in hexamethyl-phosphoramide-iV-methyl-2-pyrollidooe and conditions established for the formation of liquid crystalline solutions. ...
