摘要:
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).
摘要:
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.
摘要:
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.

摘要:
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.
摘要:
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.
摘要:
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.
摘要:
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:a) when the plastic matrix has all flat surfaces, the synthetic fabric is located on a side opposite the location of the one or more catheters and covers the entire side in area,b) when the plastic matrix is cylindrical in shape, the synthetic fabric is located in a lower portion of the cylindrical plastic matrix and coaxially arranged, andc) when the plastic matrix is of a shape other than a) and b), the synthetic fabric is located on a side facing away from a side from which irradiation occurs.
