Process for preparing partial (meth)acrylic esters of polyalcohols having different hydroxyl groups, process for their preparation, and use thereof.

Enzymatic preparation of (meth)acrylic esters

The present invention relates to a process for preparing (meth)acrylic esters of alcohols having C&#x2014;C triple bonds, to processes for their preparation, and to their use.

Enzymatic production of (meth)acrylic acid esters

Provided is a process for esterifying or transesterifying side chains in polymers, which involves esterifying or transesterifying the carboxyl group having the Rradical of a copolymer obtained by polymerizing a (meth)acrylate of formula (I), and a monomer of formula (II): wherein Rand Rare independently H or CH, Rand Rare independently H or an alkyl radical which is optionally substituted by functional groups such as acryloyl, ether, amino, epoxy, halogen or sulfonic acid groups, and n is from 1 to 40, with an alcohol in the presence of an enzyme which catalyzes the esterifying or transesterifying. Further provided is the esterified or transesterified polymer product and its use.

Process for esterifying or transesterifying side chains in polymers

The claimed invention relates to a process for preparing (meth)acrylates of N-hydroxyalkylated amides, in which open-chain N-hydroxyalkylated amides are esterified with (meth)acrylic acid or transesterified with at least one (meth)acrylic ester in the presence of at least one heterogeneous catalyst selected from the group consisting of an inorganic salt and an enzyme.

Catalyzed preparation of (meth)acrylates of N-hydroxyalkylated amides

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.

Enzymatic method for the production of microcapsules

Hyperbranched polyesters containing ethylenically unsaturated groups and obtainable by reacting

Hyperbranched polymers having ethylenically unsaturated groups

A process for preparing (meth)acrylic esters (F) of alcohols (A) having at least one epoxy group, in which at least one alcohol (A) having at least one epoxy group is esterified with (meth)acrylic acid (S) or is transesterified with at least one (meth)acrylic ester (D) in the presence of at least one enzyme, the alcoholic leaving group being stable under the reaction conditions in the case of the transesterification.

Process for producing of epoxy-containing (meth)acrylic esters, using lipases

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.

Bleach systems enveloped with polymeric layers

Process for catalytically preparing (meth)acrylates of N-hydroxyalkylated amides and use thereof.

Polyolefin waxes bearing (meth)acrylate groups, process for preparing them and their use.

Modified polyolefin waxes

A method for the production of partially esterified (meth)acrylic acid esters of polyalcohols and the use thereof.

The present invention provides a highly functional hyperbranched polyester which may be obtained by a process which comprises reacting a reaction solution containing solvent and reactants in the presence of an enzyme at a temperature above 60&#xb0; C. and a pressure above 500 mbar.

Method for producing highly functional, hyper branched polyester by means of enzymatic esterification

Enzymatic preparation of (meth)acrylic esters containing urethane groups, and their use in radiation-curable compositions.

Enzymatic production of (meth)acrylic esters that contain urethane groups

The present invention relates to a process for preparing highly functional hyperbranched polyesters which comprises reacting a reaction solution comprising solvent and
