Polyacrylic Resin III is an anionic copolymer of methacrylic acid and methyl methacrylate. By forming alkali salts, it becomes soluble in neutral to weakly alkaline media, thereby providing an enteric coating film that dissolves in intestinal fluid at a pH above 7.0.

Film-forming properties

Polyacrylic Resin III forms a colorless, transparent film. Plasticizers may be added to reduce brittleness. The film is insoluble in water, buffer solutions with a pH below 7.0, and both natural and simulated gastric fluid; however, it is soluble in neutral to weakly alkaline media and in the intestinal tract where the pH exceeds 7.0.
