Which polymerization technique (anionic or cationic) would be the best to use for the polymerization of isobutyl vinyl ether?
cationic polymerization technique would be the best for isobutyl vinyl ether.
cationic polymerization is based on capability of carbocations and other positively charged ions of adding rapidly at double bonds and reacting with heteroatoms of other organic molecules.
Vinyl ethers have a strongly electron donating alkoxy group readily form polymers on treatment with an acidic compound. polymerization in presence of an acid is cationic.
