By using an appropriate cationic polymerization system, novel polymers could be produced that retained unsaturation derived from the biobased starting material.
As a result of the much higher reactivity of the vinyl ether group compared to the unsaturation derived from the bio-based compounds and the ability to tailor the cationic polymerization process, polymerization was exclusively limited to vinyl ether groups.
Abstract Novel, partially bio-based poly(vinyl ether) copolymers derived from soybean oil and cyclohexyl vinyl ether (CHVE) were produced by cationic polymerization and investigated for application as alkyd-type surface coatings.

Depending on the type of active centre, chain-growth Polymerization can be divided into free-radical, anionic, and cationic Polymerization.
Crick reaction has been employed in combination with living polymerization techniques such as ring-opening polymerization (ROP), ring-opening metathesis polymerization (ROMP), cationic polymerization, nitric-oxide mediated radical polymerization (NMP), atom transfer radical polymerization (ATRP), and reversible addition fragmentation chain transfer polymerization (RAFT).
