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),, in which R is an aliphatically unsaturated organic radical with the valence a, A is a carboxyl group —COOH, sulfuric acid group —OSO,OH, sulfonic acid group —SO,H, phosphoric acid group —OPO(OH),, phosphonic acid group —PO(OH),, phosphorous acid group —OP(OH),, 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.
