摘要：
The invention is concerned with a polymer, polymerized from a monomer mixture comprising: (a) 70 to 95% by weight of 2-Ethylhexyl methacrylate (EHMA) and Ethyl methacrylate (EMA or 2-Ethylhexyl methacrylate (EHMA) and methyl methacrylate (MMA), (b) 2.5 to 25% by weight of one or more C2 to C6 hydroxy-alkylesters of acrylic acid or methacrylic acid, (c) 2.5 to 15% by weight of one or more C2 to C8 alkyl esters of acrylic acid or of methacrylic acid with a quaternary cationic group in the alkyl group. Disclosed is also the use of a polymer for preparing a dosage form with a sustained release profile and resistance against the influence of ethanol and the dosage form itself.
