Antimicrobial additives

The invention relates to water-insoluble polymers which promote cell proliferation, contain carboxylate and sulfonate groups and are obtainable by free radical copolymerization of one or more aliphatically unsaturated monomers containing carboxylate groups, or the correspondingly functionalized derivatives of the monomers, as component I with one or more aliphatically unsaturated monomers containing sulfonate groups, or the correspondingly functionalized derivatives of the monomers, as component II and a component III which comprises an aliphatically unsaturated monomer or several aliphatically unsaturated monomers, the correspondingly functionalized derivatives being converted into carboxylate and sulfonate groups after the copolymerization, and to a process for their preparation, wherein the polymers are useful for forming articles which promote cell proliferation.

Carboxylate-sulfonate polymers

Preparation of carboxylate-sulfonate polymers having cell proliferation-promoting properties

Antimicrobial activity is imparted to the surface(s) of an apparatus or article by polymerizing tert-butylaminoethyl methacrylate in the presence of the apparatus or article by which adhesion of the polymer to the surface(s) is achieved. In a preferred embodiment of the invention the antimicrobial monomer is graft polymerized on the surface(s).

Bioactive surface coating

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

Water insoluble bacteriophobic polymers containing carboxyl and sulfonic acid groups

Process for the preparation of antimicrobial plastics

A process for preparing molding materials having anticoagulant properties is described. Hydrophobic monomers are subjected to free-radical copolymerization with hydrophilic monomers having biospecifically active functions to produce the molding material. The molding material may then be shaped into articles which also have anticoagulant properties. These articles are extremely useful in, for example, medical applications in contact with a patient's biological fluid.

Molding materials having anticoagulant properties, their preparation and

A process for modifying the surface of a polymer substrate which comprises (1) pretreating the polymer substrate with a photoinitiator or thermoinitiator and at least one ethylenically unsaturated monomer, and (2) subjecting said pretreated polymer substrate to graft polymerization by said at least one monomer, optionally in the added presence of at least one ethylenically unsaturated monomer that is the same or different from the monomer of step (1), and products produced thereby.

Process for modifying the surface of polymer substrates by graft

Antimicrobial activity is imparted to the surface(s) of an apparatus or article by a method, comprising: copolymerizing tertbutylaminoethyl methacrylate with at least one other aliphatically unsaturated monomer in the presence of said apparatus or article by which adhesion of the copolymer to said surface(s) is achieved. In an embodiment of the invention, adhesion of the polymer coating on the apparatus or article occurs by graft copolymerization.
