General description

Vinylphosphonic acid (VPA) is an organophosphorus compound that is used in the surface treatment of metal substrates. It can be used in the preparation of poly(VPA) by radical polymerization in the presence of initiator systems and chain transfer agents. PVPA tends to have an electrolytic nature, which is useful for a variety of energy based applications.

Application

VPA based homopolymers and copolymers find usage in corrosion treatment, fuel cells, dental cement, drug delivery, and bio-mimicry.

Trisubstituted vinylphosphonates have been prepared via three-component reaction using phosphites, acetylenic esters, and aroyl chlorides in good yields. A variety of phosphites, activated acetylenes, and aroyl chlorides have been successfully employed in these reactions. In addition, three-component synthesis of vinylphosphonate

Recent studies have shown that poly(vinylphosphonate)s are readily accessible by rare earth metal-mediated group transfer polymerization (GTP). This article highlights the progress in this new field and advantages of GTP in comparison to classical anionic and radical polymerization approaches. Late
