Thermotropic Liquid Crystalline Complexes of Hydrogen-Bonded Poly(pyridylpyridinium dodecyl methacrylate) Bromide and Octylphenol

Thermotropic Liquid Crystalline Complexes of Hydrogen-Bonded Poly(pyridylpyridinium dodecyl methacrylate) Bromide and Octylphenol. Bazuin, C. Geraldine; Brodin, Christophe (Centre de Recherche en Sciences et Ingenierie des Macromolecules (CERSIM), Departement de Chimie, Universite Laval, Quebec City, QC G1K 7P4, Can.). Macromolecules, 37(25), 9366-9372 (English) 2004 American Chemical Society. CODEN: MAMOBX. ISSN: 0024-9297. DOCUMENT TYPE: Journal CA Section: 36 (Physical Properties of Synthetic High Polymers) Section cross-reference(s): 75 An ion-contg. polyamphiphile, poly(w-pyridylpyridinium dodecyl methacrylate) bromide, was successfully complexed with 4-octylphenol by hydrogen bonding, with no interference from the ionic moieties. Hydrogen bonding of the surfactant to the polymer is virtually complete up to near-equimolar phenol/pyridyl ratios. The complexation generates a well-behaved thermotropic liq. cryst. system from a low-melting surfactant and a polymer with ill-defined mesomorphism. The complex melts at relatively high temps. into a liq. cryst. (smectic A) phase before becoming isotropic. The long period of the mesophase is almost identical to that of the polyamphiphile alone, is between the calcd. lengths of the uncomplexed and complexed polymer repeat units, and is essentially independent of the complex stoichiometry. This can be rationalized by the same model presented in a previous publication for an ionically complexed polyamphiphile-surfactant system.Except for chemicals metioned above, 1806-26-4 and 260050-18-8 are also used. .
