摘要：
The present invention relates to a process for producing a microcapsule dispersion comprising microcapsules comprising a hydrophilic capsule core and a capsule wall polymer, wherein a water-in-oil emulsion comprising a hydrophobic diluent as continuous phase, and the hydrophilic capsule core material, a monomer composition and an amphiphilic polymer is produced and then the monomers are free-radically polymerized, where the monomer composition comprises 30 to 100% by weight of one or more monomers selected from C1-C24-alkyl esters of acrylic acid and/or methacrylic acid (monomers I), 0 to 70% by weight of one or more monomers selected from acrylic acid, methacrylic acid, maleic acid, acrylic acid esters and/or methacrylic acid esters which carry hydroxy and/or carboxy groups (monomers II), 0 to 50% by weight of one or more monomers which has two or more ethylenically unsaturated radicals, (monomers III) and 0 to 30% by weight of one or more other monomers (monomers IV), in each case based on the total weight of the monomers, and the amphiphilic polymer is obtainable by free-radical polymerization of a monomer composition comprising at least one ethylenically unsaturated hydrophilic monomer and at least one ethylenically unsaturated hydrophobic monomer, to the microcapsules obtainable thereby, and to their use for the delayed release of active ingredients for construction, cosmetics, detergents and cleaners or crop protection applications.La presente invención se refiere a un procedimiento para producir una dispersión de microcápsular que comprende microcápsulas que a su vez comprenden un núcleo de capsular hidrófilo y un polímero de pared de cápsula, en el que una emulsión de agua en aceite que comprende un diluyente hidrofóbo como base continua, y el material del núcleo capsular hidrófilo, una composición monomérica y un polímero anfifílico es producido y entonces los monómeros son polimerizados por radicales libres, en donde la composición monomérica comprende 30
