Abstract
The invention relates to water-insoluble, bacteriophobic and optionally cell proliferation-inhibiting polymers obtainable by free-radical polymerization of (a) at least one monomer of the general formula R--(A).sub.a, in which R is an aliphatically unsaturated organic radical with the valence a, A is a carboxyl group --COOH, sulfuric acid group --OSO.sub.2 OH, sulfonic acid group --SO.sub.3 H, phosphoric acid group --OPO(OH).sub.2, phosphonic acid group --PO(OH).sub.2, phosphorous acid group --OP(OH).sub.2, a phenolic hydroxyl group or a salt of one of the groups, and a is 1, 2 or 3, with the proviso that, if the monomer of the formula I contains a carboxyl group --COOH or a carboxylate group, either this monomer contains at least one further radical A having a different one of the definitions specified for A, or at least one further monomer of the formula I is also used in which A has a different one of the definitions specified for A; and (b) at least one other aliphatically unsaturated monomer, wherein the polymers are useful for forming bacteriophobic or cell proliferation-inhibiting articles.
