Paper Abstract

The temperature dependence of hydrodynamic properties of three new LC comb-like poly(alkoxy-4- ethylphenylbenzoate)(methyl)-siloxanes) with different alkyl spacers between the backbone and the mesogenic side groups, and low-molar-mass compounds as models, analogous to macromolecule side chains has been investigated. Temperature-reversible aggregation of the molecules of these compounds in benzene solution was observed at temperatures below 26 degrees C. This phenomenon was found to depend on the degree of bonding of thermotropic mesogens to the backbone chain and on the aliphatic spacer chain length.
