Patent number: 9238715Abstract: An object of the present invention is to provide a polymerizable composition capable of providing antimicrobial properties to ophthalmic and medical devices relatively inexpensively with ease, and an antimicrobial composition obtained by polymerizing the polymerizable composition. A polymerizable composition for ophthalmic or medical use comprising an epsilon-polylysine having (meth)acryloyl group is provided. The content of the epsilon-polylysine having (meth)acryloyl group in the polymerizable composition is preferably about 0.1 to 99% by weight, based on the whole amount of the composition. A coating agent for ophthalmic or medical use comprising the above polymerizable composition, an antimicrobial composition for ophthalmic or medical use obtained by polymerizing the above polymerizable composition, an ophthalmic or medical device comprising the antimicrobial composition, and a contact lens comprising the antimicrobial composition are also provided.Type: GrantFiled: July 5, 2013Date of Patent: January 19, 2016Assignee: Nanyang Technological UniversityInventors: Bee Eng Mary Chan, Chuncai Zhou, Susanna Su Jan Leong, Matthew Wook Chang, Peng Li, Xiaobao Qi, Mouad Lamrani

Patent number: 6844030Abstract: This invention concerns a process for modifying a polymeric substrate by contacting the surface with a photoreactive solution of an inorganic photochemical electron donor while irradiating the surface with actinic radiation. Patterns of modified and unmodified surfaces can be produced. Polymeric substrates with modified surfaces may be effectively bonded to polymer films to form composite articles. The process has particular applicability to the surface modification of fluorinated polymers.Type: GrantFiled: December 14, 2001Date of Patent: January 18, 2005Assignee: 3M Innovative Properties CompanyInventors: Naiyong Jing, George Van Dyke Tiers

Patent number: 6827875Abstract: The present invention relates to new blocked polyisocyanates with which high-grade, emission-free coatings and lacquer coatings with reduced yellowing values can be obtained, to a method of producing them, and to the use thereof in one-component polyurethane systems, particularly as crosslinking agents in automobile primer surfacers.Type: GrantFiled: June 28, 2002Date of Patent: December 7, 2004Assignee: Bayer AktiengesellschaftInventors: Michael Schelhaas, Christoph Gürtler
-
Patent number: 5977255Abstract: The present invention relates to a method for curing a hydrocarbon polymer having at least 2 glycidoxy groups in its molecule, said method comprising reacting the hydrocarbon polymer with a curing amount of an organosilicon compound having at least 2 nitrogen-bonded hydrogen groups as well as at least one silicon-bonded group selected from --R or --OR in its molecule, wherein R is selected from alkyl radicals having 8 to 18 carbon atoms or alkenyl radicals having 8 to 18 carbon atoms.Type: GrantFiled: October 6, 1997Date of Patent: November 2, 1999Assignee: Dow Corning CorporationInventors: Irene Q. Li, Toshio Suzuki

Patent number: 5459222Abstract: Polyurethanes and polyesters are described which are the reaction products of an aromatic, aliphatic or cycloaliphatic diisocyanate, or of a diacid or diacid derivative respectively, with a diol containing a pendent UV-absorbing moiety, optionally also with one or more other diols or diamines. These UV-absorbing polycondensates can be applied to the surfaces of substrates by exhaustion methods or by spraying and act to protect polymers and dyes from degradation by UV radiation. They are therefore useful, either alone or in combination with other coating materials, for the treatment of wood, paper, textiles, leather or other surfaces which are exposed to degrading radiation.Type: GrantFiled: June 4, 1993Date of Patent: October 17, 1995Assignee: Ciba-Geigy CorporationInventors: Juliana Rodgers, Istvan Borsody, Athanasios Karydas, Robert A. Falk, Karl F. Mueller, Michele Kovaleski
