Patent number: 6203856Abstract: 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.Type: GrantFiled: September 14, 1999Date of Patent: March 20, 2001Assignee: Huels AktiengesellschaftInventors: Peter Ottersbach, Frank Hill, Christine Anders

Patent number: 6160056Abstract: 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.Type: GrantFiled: March 2, 1998Date of Patent: December 12, 2000Assignee: Vestolit GmbHInventors: Marcel Jozefowicz, Veronique Migonney, Heinz Hermann Meyer, Thomas Neu, Axel Stieneker, Christine Anders, Peter Ottersbach

Patent number: 6096369Abstract: 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.Type: GrantFiled: June 29, 1998Date of Patent: August 1, 2000Assignee: Huels AktiengesellschaftInventors: Christine Anders, Robert Hans-Jorg Jacobasch, deceased, by Margareta Ute Dagmar Jacobasch, heir, by Kathrin Gotz nee Jacobasch, heir, by Lutz Jacobasch, heir, by Susanne Jacobasch, heir, Volker Steinert, Stefan Zschoche
