A survey of the stereochemical aspects relevant to the cationic polymerization of chiral alkyl vinyl ethers has been presented. Accordingly the routes to the preparation of optically active poly(alkyl vinyl ether)s by starting both from optically active monomers and racemic ones have been presented. In particular, to approach the mechanistic aspects of the stereospecific heterogeneous catalytic systems based on alkyl or alkoxy aluminum and sulphuric acid, the activity of soluble organoaluminum sulphates has been investigated. The kinetic trend of the polymerization of some optically active vinyl ethers has been determined simply by optical rotation measurements. On the basis of the presented data a coordinate polymerization mechanism has been proposed for the multicomponent catalyst introduced by Vandenberg.
