Silyl vinyl ethers can be polymerized at room temperature and in high yield by initiation with electrophiles, e.g. aldehydes, in the presence of a Lewis acid catalyst. This polymerization, called aldol group transfer polymerization, is living and permits good molecular weight control. Narrow molecular weight distribution is usually obtained. The silylated polymerization products can be hydrolyzed to poly(vinyl alcohol) and coupled via the reactive end group with other functional polymers to give block copolymers. Other block and graft polymers containing the hydrophilic poly(vinyl alcohol) segment can be obtained by initiating aldol group transfer polymerization with mono‐ or multifunctional polymeric initiators.
