Abstract
The invention provides methods for producing sheetlike structures or shaped articles that comprise latent heat storage media, characterized in that mixtures comprising one or more microcapsules which contain one or more latent heat storage media, and one or more polymers based on one or more ethylenically unsaturated monomers selected from the group consisting of vinyl esters, (meth)acrylic esters, vinylaromatics, olefins, 1,3-dienes and vinyl halides, are processed by means of thermoplastic shaping techniques.
Claims8
A process for the production of moldings or sheet materials comprising latent heat accumulators, wherein
- a dry mixture comprising one or more microcapsules and one or more protective-colloid-stabilized, water-redispersible polymer powders of polymers based on one or more ethylenically unsaturated monomers selected from the group consisting of vinyl esters, (meth)acrylic esters, vinylaromatics, olefins, 1,3-dienes, and vinyl halides, wherein said microcapsules comprise one or more latent heat accumulators,
- is processed by a thermoplastic forming technique selected from the group consisting of extrusion, injection molding, pressing, and calendering.
