Abstract:
A pharmaceutical presentation comprising the graft polymers obtained by polymerization ofa) at least one vinyl ester of aliphatic C1-C24-carboxylic acids in the presence of b) polyethers of the general formula I, â€ƒin which the variables have, independently of one another, the following meanings: R1 hydrogen, C1-C24-alkyl, R9â€”C(&boxH;O)â€”, polyalcohol residue; R8 hydrogen, C1-C24-alkyl, R9â€”C(&boxH;O)â€”; R2 to R7 â€”(CH2)2â€”, â€”(CH2)3â€”, â€”(CH2)4â€”, â€”CH2â€”CH(CH3)â€”, â€”CH2â€”CH(CH2â€”CH3)â€”, â€”CH2â€”CHOR10â€”CH2â€”; R9 C1-C24-alkyl; R10 hydrogen, C1-C24-alkyl, R9â€”C(&boxH;O)â€”; A â€”C(&boxH;O)â€”Oâ€”, â€”C(&boxH;O)â€”Bâ€”C(&boxH;O)â€”Oâ€”, â€”C(&boxH;O)â€”NHâ€”Bâ€”NHâ€”C(&boxH;O)â€”Oâ€”; B â€”(CH2)tâ€”, arylene, optionally substituted; n 1 to 8; s 0 to 500; u 1 to 5000; v 0 to 5000; w 0 to 5000; x 1 to 5000; y 0 to 5000; z 0 to 5000, wherein the molecular weight of the polyethers is in the range from 300 to 100,000, as coating agent, binder and/or film-forming excipient in pharmaceutical presentations.
