POLYMERS AND OLIGOMERS OF BILE ACID DERIVATIVES, PROCESS FORTHEIR PREPARATION AND THEIR USE AS PHARMACEUTICALS

摘要

Polymeric and oligomeric bile acids are described which can be prepared by polymerization of monomeric bile acids of the formula I G-X-A (I) in which G, X and A have the given meanings or by copolymerization with a monomer of the formula IV <IMG> in which R9 and R10 have the given meanings, or by copoly- merization with N-vinylpyrrolidone or its derivatives, and/or by copolymerization with ethylenically unsaturated dicarboxylic anhydrides and ethylenically unsaturated dicarboxylic acids each having 2 to 6 carbon atoms; their esters or half esters, alkyl esters having 1-6 carbon atoms, cycloalkyl esters having 5 to 8 carbon atoms, benzyl esters or phenyl esters being understood as esters. They can be used as pharmaceuticals, foodstuff additives, formulation auxiliaries and detergents.
