Patent application numberDescriptionPublished
20080217201Container Made From Plastics Materials With A Polymeric Organofluorine Interior Coating For Active-Compound Formulations For Crop Protection Or Protection Of Materials - The present invention relates to the use of containers comprising plastic materials, whose inner walls are provided with a polymeric, organofluorine coating which has a multiplicity of perfluoroalkyl groups on its surface, for active substance formulations for crop protection or material protection.09-11-2008
20100120617Enzymatic Method for the Production of Microcapsules - Process for producing microcapsules comprising an effect-substance-containing capsule core and a polymer-containing capsule covering, comprising the formation of the capsule covering by means of enzyme-catalyzed polymerization of monomers which are present in an inverse miniemulsion; and also microcapsules and dispersions. Use of said microcapsules and dispersions comprising microcapsules as component in colorants, cosmetics, pharmaceuticals, crop protection agents, fertilizers, additives for foods or animal feed, auxiliaries for polymers, paper, textile, leather or detergents and cleaners.05-13-2010
20100305256METHOD FOR HYDROPHOBING TEXTILE MATERIALS - The process for finishing textile materials by treatment with at least one aqueous liquor which comprises at least one organic polymer and at least one organic or inorganic solid in particulate form, wherein the organic or inorganic solid or solids are present in the liquor in a fraction of at least 5.5 g/l.12-02-2010
20110313097POLYMERS WITH SACCHARIDE SIDE GROUPS AND THEIR USE - A water-soluble or water-dispersible copolymer comprises copolymerized units a) of at least one ethylenically unsaturated monomer with a saccharide side group and b) of at least one hydrophilic ethylenically unsaturated monomer different from (meth)acrylamide, where the weight fraction of the ethylenically unsaturated monomers with a saccharide side group is 5 to 95% by weight. The copolymers exhibit high affinity to inorganic surfaces or hydrophilic fibers, such as cotton. They serve as soil release and/or graying-inhibiting polymers in textile detergents or minimize the risk of microbial colonization of materials coated therewith.12-22-2011
20120016114PROCESS FOR THE PREPARATION OF MONOETHYLENICALLY UNSATURATED GLYCOSYLAMINES - The present invention relates to a process for the preparation of monoethylenically unsaturated glycosylamines, in which an aldehyde sugar is reacted with a primary aliphatic amine or ammonia in aqueous medium and, without interim isolation, is reacted with the anhydride of a monounsaturated carboxylic acid, or an aldehyde sugar is reacted directly with allylamine, and to a process for the preparation of polymers which comprise N-acylated glycosylamine groups in copolymerized form, and to novel unsaturated N-maleinylated glycosylamines.01-19-2012
20120028307ENZYMATIC PRODUCTION OF AN ETHYLENICALLY UNSATURATED GLYCOSIDE USING POLYSACCHARIDES - Ethylenically unsaturated glycosides of formula I02-02-2012
20120028308ENZYMATIC PRODUCTION OF AN ETHYLENICALLY UNSATURATED GLYCOSIDE - Ethylenically unsaturated glycosides of formula I02-02-2012
20120088891PROCESS FOR THE PREPARATION OF UNSATURATED ACYLAMIDOALKYLPOLYHYDROXY ACID AMIDES - The present invention relates to a process for the preparation of unsaturated acylamidoalkylpolyhydroxy acid amides by reacting the reaction product of polyhydroxy acid lactone and aliphatic diamine with the anhydride of a monounsaturated carboxylic acid, to the unsaturated acylamidoalkylpolyhydroxy acid amides and also to a process for the preparation of polymers of unsaturated acylamidoalkylpolyhydroxy acid amides.04-12-2012
