Abstract
The synthesis of the series of new liquid crystalline comb-shaped poly(vinyl ether)s with cyanbiphenyl mesogenic groups is reported. Methylenic spacer groups of the different lengths (n=2–6,11) were used. Polymers were prepared by cationic polymerization corresponding vinyl ethers. The influence of molar mass and molar mass distribution on the mesomorphic properties and phase transitions has been studied. The effect of chemical structure of the main chain on the mesomorphic properties is discussed.
