Use of water-insoluble polymers (P) is claimed as bacteriophobic materials. (P) are obtained by radical polymerisation of (a) at least one monomer of formula R-(A)a (I) and (b) at least one other aliphatic unsaturated monomer. R = an olefinic organic group; A = COOH, OSO2OH, SO3H, OPO(OH)2, PO(OH)2, OP(OH)2, a phenolic OH group or a salt or ester of these groups; a = 1-3: provided that when A = COOH or carboxylate, then either this monomer contains another A group with a different definition, or the monomer is used with another monomer whose A group has a different meaning. Also claimed are (1) new polymers (P1), where (P1) contains two monomer components: (a') aliphatically unsaturated monomers; and (b') one or more aliphatically unsaturated monomers; where either (a') contains monomers (a1) with carboxyl and/or carboxylate groups or their functional derivatives and monomers (a2) with aliphatic, unsaturated monomers containing sulphonic acid and/or sulphonate groups or their functional derivatives; or the monomers of (a') contain both the carboxylate and the sulphonate groups in a single molecule. In the obtained polymer, the functionalised derivatives are converted back to carboxylic acid, sulphonic acid, carboxylate or sulphonate, at least at the surface; (2) the use of (P) and (P1) to manufacture materials with bacteriophobic surfaces, especially textiles, furniture, devices, wall and floor coverings, flooring, window frames, tubing or piping, storage containers, packaging and medicinal devices; and to produce bacteriophobic coatings for these and for furniture, containers, packing materials, window frames and medical articles; and the use of carboxylate- and sulphonate- containing (P) and (P1) to produce coatings on medical-technical objects made of ceramic, metal or plastic; and (3) objects with a bacteriophobic surface made from carboxylate- and sulphonate- containing (P) and (P1). |
