The invention relates to the application of microcapsules I with one or more lipophilic substances as core material. Said lipophilic substances have a solid/liquid phase transition at a temperature ranging from -20 to 120 ~C and a polymer which is used as a shell and can be obtained by means of radical polymerization of a monomer mixture containing 30 to 100 wt.%, referring to the total weight of the monomers, one or more C1-C24-alkyl esters of the acrylic acid and/or methylacrylic acid (monomer I), 0 to 80 wt.%, referring to the total weight of the monomers, one bi- or polyfuntional monomer (monomer II) which is insoluble or poorly soluble in water, and 0 to 40 wt.%, referring to the total weight of the monomers, and other monomers (monomer III). The microcapsules can be used as latent heat accumulators. The invention also relates to novel microcapsules Ia, spray-dried microcapsules Ia', methods for the production thereof, and to shaped bodies and coating masses containing said microcapsules.

L'invention concerne l'utilisation de microcapsules I comprenant une ou plusieurs substances lipophiles composant le noyau et présentant une transition de phase solide à liquide située dans une plage de température de -20 à 120 ·C, ainsi qu'un polymère constituant l'enveloppe et obtenu par polymérisation radicale d'un mélange de monomères contenant: 30 à 100 % en poids, par rapport au poids total des monomères, d'un ou de plusieurs esters d'alkyle C¿1?-C¿24? d'acide acrylique ou méthacrylique (monomère I); 0 à 80 % en poids, par rapport au poids total des monomères, d'un monomère bi- ou polyfonctionnel (monomère II), non soluble ou difficilement soluble dans l'eau; 0 à 40 % en poids, par rapport au poids total des monomères, d'autres monomères (monomère III), en tant qu'accumulateurs de chaleur latente. Elle concerne également de nouvelles microcapsules Ia séchées par pulvérisation, des procédés servant à les préparer, des corps façonnés et des matériaux de revêtement contenant ces microcapsules.
