Gantrez™ AN polymers
Chemistry: Vinyl Ether polymers and copolymers
SDS Link >Gantrez™ AN polymers are synthetic, alternating copolymers of methyl vinyl ether (MVE) and maleic anhydride available in a range of molecular weights. Although the anhydride polymers (AN grades) are not directly useable in oral care products, they are used as base polymer for making polymer salts used as bioadhesives in denture adhesive applications.
When Gantrez™ AN polymers anhydrides are dispersed in water, the anhydride side-chain hydrolyzes to produce free diacid solutions that are directly useable in oral care products. Gantrez™ polymer diacids are available as Gantrez S polymers
