Bioactive surface coating using macroinitiators

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).

Process for the preparation of antimicrobial articles

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

The invention relates to a process for making the surface of polymeric substrates hydrophilic, which includes coating the surface of a polymeric substrate with a solution of a macroinitiator, wherein the macroinitiator includes a polymer framework and side chains attached to the polymer framework, and wherein at least one of the side chains includes at least one free-radical-forming group. Optionally, a hydrophilic vinyl monomer or monomers may then be free-radical polymerized or graft polymerized onto the macroinitiator-coated substrate. A crosslinking vinyl monomer may optionally be used together with the macroinitiator or the hydrophilic vinyl monomer. The invention also relates to polymeric substrates having hydrophilic surfaces obtained by the process, and articles that include the hydrophilic polymeric substrates.

Process for hydrophilicizing the surface of polymeric substrates with a

A method for making antimicrobial, blood-compatible surfaces is provided, articles having surfaces made by this method, and the use of these articles in fields where controlling the spread of microbes and blood-compatibility are important. Such fields include the medical field, where it is critical to eliminate infection causing microbes and reduce the number of dangerous blood clots in patients.

Method of making a blood-compatible antimicrobial surface

A process for producing a flexible plastic molding with one or more catheters or tubes embedded equidistantly therein which comprises firmly clamping the catheters or tubes in a liquid or semi-gelled paste comprising a precursor of the plastic material of the molding, in a gelling or hardening mold, and then carrying out complete gelling or hardening, and a product made by the process.

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.

A hydrophilic coating on a polymeric substrate is prepared by subjecting at least one hydrophilic vinyl monomer to radiation-induced graft polymerization on an activated substrate surface.

Hydrophilic coating of surfaces of polymeric substrates

A plastic catheter system for irradiation therapy by the afterloading method, made from: a flexible plastic matrix having one or more catheters or sheaths embedded therein, and having a synthetic fabric contained within the plastic matrix or on a side of the plastic matrix, wherein:

Flexible adaptable plastic elements with equidistantly embedded
