Patent number: 9217080Abstract: The present invention concerns microcapsules comprising a capsule core and a capsule wall, the capsule wall being constructed from 30% to 90% by weight of one or more C1-C24-alkyl esters of acrylic and/ or methacrylic acid, acrylic acid, methacrylic acid and/or maleic acid (monomers I), 10% to 70% by weight of a mixture of divinyl and polyvinyl monomers (monomers II), the fraction of polyvinyl monomers being in the range from 2% to 90% by weight based on the monomers II, and also ?0% to 30% by weight of one or more miscellaneous monomers (monomer III), all based on the total weight of the monomers, a process for their production and their use in textiles, bindered building materials and heat transfer fluids.Type: GrantFiled: April 4, 2013Date of Patent: December 22, 2015Assignee: BASF SEInventors: Marc Rudolf Jung, Hans-Peter Hentze, Rainer Dyllick-Brenzinger, Dieter Niederberger, Hans Willax
