METHACRYLIC ACID-METHYL METHACRYLATE COPOLYMER (1:2)
This product is an anionic copolymer of methacrylic acid and methyl methacrylate. It corresponds to the "Methacrylic Acid and Methyl Methacrylate Copolymer (1:2)" monograph in the United States Pharmacopeia (USP). It forms salts upon contact with alkali and is soluble in neutral to weakly alkaline media, thereby providing an enteric coating that dissolves in intestinal fluid at pH 7.0 and above.

Film-forming properties
Films made from methacrylic acid- methyl methacrylate copolymer (1:2) are colorless and transparent. With the addition of plasticizers to reduce brittleness, the film is insoluble in water, buffer solutions with a pH below 7.0, and natural or simulated gastric fluid (SGF)s; it is soluble in neutral to weakly alkaline media and in the digestive tract at pH 7.0 and above.
Product Applications
Coating for tablets, granules, and pellets:
Packaging
Fiber drums lined with double- layer polyethylene bags; 10 kg per drum
Storage
Store in a sealed container at room temperature
