Abstract

Thermoplastic materials which comprise a copolymer of PA1 (A) 16 to 40 wt % of acrylic and/or methacrylic acid; PA1 (B) 30 to 80 wt % of methyl acrylate; and PA1 (C) 0 to 40 wt % of another alkyl ester of acrylic and/or methacrylic acid and perhaps conventional auxiliaries for drug coatings are suitable for the production of drug coatings which are soluble in intestinal juices, such as tablet coatings, dies, films, capsules, or multipart dosage units.
