Webster`s cationic initiating system (HO{sub 3}SCF{sub 3}/SMe{sub 2}) (Macromolecules, 23, 1918 (1990)) was shown by us (for a review see Adv. Mater., 4, 548 (1992)) to polymerize, via a living mechanism, mesogenic vinyl ethers which contain a large variety of functional groups. This is mostly because SMe{sub 2} is a softer nucleophile than any of the functional groups available in these monomers. The molecular engineering of side-chain liquid crystalline polymers with conventional and complex architectures via this polymerization technique will be discussed.
