    I-Poly(Methylvinylether/Maleic Acid)Usawoti Oxubile

    I-copolymer ehlinzekwa ngesimo sempushana, incibilika kancane kancane emanzini okuholela ezixazululweni ezinombala we-amber ezine-viscosity ephezulu kanye nokunamathela. Isetshenziswa njenge-bioadhesive kuma-adhesive amazinyo, nanjenge-mucoadhesive ekulethweni kwezidakamizwa kulwelwesi lwamafinyila.Futhi amabhuloho kasawoti e-Calcium athuthukisa izakhiwo ezihlangene.Ingamandla amahle kakhulu okunamathela Okumanzi, Ukubamba Okuhlala Isikhathi Eside,I-Mucoadhesive eyenza ukulethwa kulwelwesi lwamafinyila. Ama-Paremeter Abalulekile Ezobuchwepheshe: Ukubukeka Okumhlophe kuya kokumhlophe okuyimpushana Amanzi ...
