Latent heat storage medium

The present invention makes available an additive for stabilization of sodium acetate trihydrate, which can be obtained by emulsion polymerization of at least one hydrophilic monomer selected from among acrylic acid and acrylic acid derivatives with an acid group and a redox initiator system. Furthermore, a method for producing the additive, a storage medium of a latent heat storage unit, containing sodium acetate trihydrate and the additive, a method for stabilizing a storage medium of a latent heat storage unit, as well as the use of the additive as a stabilizer for sodium acetate trihydratein a latent heat storage unit are made available. 本发明提供种用于稳定三水合乙酸钠的添加剂，该添加剂可通过选自丙烯酸和具有酸根的丙烯酸衍生物中的至少种亲水性单体和氧化还原引发剂体系的乳液聚合而获得。此外，本发明还提供种用于制备该添加剂的方法，种潜热存储物的包含三水合乙酸钠和添加剂的存储介质，种用于稳定潜热存储物的存储介质的方法，以及种该添加剂在潜热存储物中作为三水合乙酸钠的稳定剂的应用。
