The invention further relates to a method for the production of said microcapsules, and to the use thereof in binding building materials, textiles and heat transfer fluids.
Abstract:
The invention relates to microcapsule dispersions containing microcapsules comprising a hydrophilic capsule core and a capsule wall polymer, which capsule wall polymer can be obtained by polymerizing a monomer composition comprising 25 to 95 wt% of one or more C1-C24 alkyl and/or glycidyl esters of acrylic acid and/or methacrylic acid, up to 75 wt% of one or more hydrophilic monomers selected from acrylic acid esters and/or methacrylic acid esters that bear hydroxy and/or carboxy groups, and allyl gluconamide, 0 to 40 wt% of one or more compounds having two or more ethylenically unsaturated groups, wherein the microcapsules are dispersed in a hydrophobic diluent. The invention further relates to the microcapsules, to a method for producing the microcapsules, and to the use of the microcapsules for the delayed release of active ingredients for construction, cosmetic, or plant-protection applications.
