Abstract:
A method of using, as latent heat storage media, microcapsules I comprising as core materials one or more lipophilic substances whose solid/liquid phase transition is within the range from -20 to 120.degree. C. and as shell a polymer obtainable by free-radical polymerization of a monomer mixture comprisingfrom 30 to 100% by weight, based on the overall weight of the monomers, of one or more C.sub.1 -C.sub.24 -alkyl esters of acrylic and/or methacrylic acid (monomer I), from 0 to 80% by weight, based on the overall weight of the monomers, of a bi- or polyfunctional monomer (monomer II) which is insoluble or of low solubility in water, andfrom 0 to 40% by weight, based on the overall weight of the monomers, of other monomers (monomers III).
