Polymethyl vinyl / maleic anhydride
Functional Category
Bioadhesive material; color dispersant; complexing agent; emulsion stabilizer; film-forming agent; viscosity-increasing agent.
Applications in Pharmaceutical Formulation or
Technology
Poly(methylvinyl ether/maleic anhydride) copolymers and derivatives are used in denture adhesive bases, controlled-release coatings, enteric coatings, ostomy adhesives, transdermal patches, toothpastes, mouthwashes, and transdermal
gels. Gantrez AN-119 has been used to manufacture specific bioadhesive ligand-nanoparticle conjugates to aid gastrointestinal retention for oral drug delivery applications. Gantrez has also beenused to develop novel polyethylene surface-modified medical devices with enhanced hydrophilicity and wettability.
Description
In the solid state, poly(methylvinyl ether/maleic anhydride) copolymers are a white to off-white free flowing, odorless,
hygroscopic powders. In solution, poly(methylvinyl ether/maleic anhydride) is a slightly hazy, odorless, viscous liquid.
