Poly(Methylvinylether/Maleic Acid) Mixed Salts Copolymer | |
INCI Name | Calcium/Sodium PVM/MA Copolymer |
CAS № | 62386-95-2 |
Chemical structure | |
Properties | The copolymer, supplied in powder form, is slowly soluble in water resulting in amber-colored solutions with high viscosity and adhesivity. It is used as a bioadhesive in denture adhesives, and as mucoadhesive for drug delivery to mucous membranes. |
Applications | MP955 polymer, a mixed sodium/calcium salt copolymer, can be used directly in the formulation of a denture adhesive. In denture adhesives the salts provide excellent wet adhesive strength and duration of hold. |
