Patent application numberDescriptionPublished
20100010244Method For Producing Fatty Acid Alkanol Amides - The invention relates to a method for producing fatty acid alkanol amides by reacting at least one amine that contains at least one primary or secondary amino group and at least one hydroxyl group with at least one fatty acid to form an ammonium salt, said ammonium salt being subsequently converted into the alkanol amide by means of microwave radiation.01-14-2010
20100032284Method For Producing Alkaline (Meth)Acrylamides - The invention relates to a method for producing alkaline amides or imides of ethylenically unsaturated C02-11-2010
20100081843Method For Producing Tertiary Amides Of Alkylphenyl Carboxylic Acids - The invention relates to a method for producing tertiary amides of alkylphenyl carboxylic acids by reacting at least one secondary amine with at least one alkylphenyl carboxylic acid to form an ammonium salt, said ammonium salt being subsequently converted into the tertiary amide by means of microwave radiation.04-01-2010
20100116642Method For Producing Alkaline Fatty Acid Amides - The invention relates to a method for producing alkaline fatty acid amides by reacting at least one amine that contains at least one primary or secondary amino group and at least one tertiary amino group with at least one fatty acid to form an ammonium salt, said ammonium salt being subsequently converted into the alkaline amide by means of microwave radiation.05-13-2010
20100273910POLYNITRONES AND USE THEREOF FOR CROSS-LINKING UNSATURATED POLYMERS - The present invention relates to polyfunctional nitrones (optionally in the form of nitrone-terminated polymers) and to their use as crosslinking agents and matting agents, preferably for producing stable molding compounds, knifing fillers, and use thereof in inks, coatings, and adhesives. Low crosslinking temperatures characterize the invention. Through the use of polyfunctional nitrones it is possible for all unsaturated polymers to be cured, solidified and/or structured at low temperatures, preferably without use of a catalyst. Depending on the amount of nitrone-terminated polymers and/or low molecular mass polyfunctional nitrone used it is possible to exert a strong influence over the optical and the mechanical properties of the coated surfaces. By optical properties are meant, among others, the gloss of the coating systems and the surface structuring, e.g., the matt effect.10-28-2010
20100324165Ophthalmological Composition And Use Thereof - The subject matter of the present invention is an ophthalmologic composition having an UV absorber and a violet absorber, wherein a high transmission is achieved in the blue light spectrum, and an eye implant, in particular an intraocular lens, which is produced with this ophthalmologic composition.12-23-2010
20110028667Copolymer and Ophthalmological Composition - The invention relates to a copolymer, which includes 20 to 95 percent by weight, based on the total weight of the copolymer, of structural units derived from at least one hydrophilic monomer, and 5 to 80 percent by weight, based on the total weight of the copolymer, of structural units derived from at least one monomer according to the general formula I02-03-2011
20110046252REACTION RESIN BASED ON AN UNSATURATED POLYESTER, VINYL COMPOUNDS AND HYDROCARBON NANOTUBES THAT CAN BE CURED RADICALLY - The present invention relates to reaction resins based on an unsaturated polyester, one or more vinyl compounds and hydrocarbon nanotubes that can be cured radically, wherein hydrocarbon nanotubes are covalently bound to the unsaturated polyester.02-24-2011
