Poly(methyl vinyl ether-alt-maleic anhydride)
Poly(methyl vinyl ether-alt-maleic anhydride) CAS 9011-16-9 is an anhydride-functional alternating copolymer widely used as a dispersant, binder and rheology modifier in coatings, adhesives, inks and specialty polymer formulations. The polymer contains alternating methyl vinyl ether and maleic anhydride repeat units, offering hydrophilic-hydrophobic balance and reactive anhydride groups that enable further chemical modification or crosslinking. Commercially this copolymer is favored for its film-forming ability, good adhesion to inorganic and organic substrates, and ability to stabilize pigments and fillers in aqueous and solventborne systems.
