PROBLEM TO BE SOLVED: To provide a substitutional method for modifying poly(meth)acrylates.SOLUTION: The method for transesterifying or esterifying side chains in polymers comprises the following steps (a) and (b): (a) a process for producing copolymer which is obtained by polymerizing (aa) at least one (meth)acrylates of general formula (I) [chemical formula 1] as component A, and (ab) at least one monomer of general formula (II) [chemical formula 2] as component B, and (b) a process for transesterifying or esterifying the carboxyl group containing the radical Rwith an alcohol in the presence of an enzyme catalyzing the transesterification or esterification.
Abstract:
The present invention relates to nucleic acids encoding triacylglycerol lipases, to vectors comprising such nucleic acids, to host cells comprising such nucleic acids or vectors, to methods of expressing triacylglycerol lipases in prokaryotes, to methods of detecting and producing triacylglycerol lipases, to triacylglycerol lipases which can be obtained in this manner, and to the use of triacylglycerol lipase-encoding nucleic acids, vectors and recombinant host cells for the abovementioned methods.
Abstract:
The invention relates to a method for the production of microcapsules that contain a capsule core containing an effective substance and a capsule shell containing a polymer, comprising the formation of the capsule shell by means of the enzyme-catalyzed polymerization of monomers that are present in an inverse mini-emulsion; and microcapsules and dispersions. The invention relates to the use of said microcapsules and dispersions containing microcapsules as components in dyes, cosmetics, pharmaceuticals, phytosanitary agents, fertilizers, additives for foods or animal feeds, adjuvants for polymers, paper, textiles, leather, or detergents and cleaning agents.
Abstract:
The present invention provides a process for producing microcapsules. The microcapsules have an effect-substance-containing capsule core and a polymer-containing capsule covering. The capsule covering is formed by enzyme-catalyzed polymerization of monomers which are present in an inverse miniemulsion, as well as microcapsules and dispersions. The present invention also provides for using the microcapsules and microcapsule dispersions as components in colorants, cosmetics, pharmaceuticals, crop protection agents, fertilizers, and additives for foods or animal feed.
Abstract:
The present invention relates to a process for preparing (meth)acrylic esters of alcohols having C—C triple bonds, to processes for their preparation, and to their use.
Abstract:
The invention relates to a bleach system comprising at least one component selected from bleach, bleach activator or bleach catalyst, wherein the bleach system is enveloped with at least one polymer layer and the polymer has urethane and urea groups. The inventive bleach system and detergent formulations comprising this bleach system are suitable for washing or cleaning textiles or dishware. (No suitable figures)
