Ashland | Gantrez™ AN polymers
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.
