Abstract
The invention provides a polymer composition which contains a bound heat accumulating phase change material which is in the form of a solid or a paste. This composition is so stable and has such a solid form that it may be easily heated up to 180 (200)° C. and mechanically treated without changing the structure and the composition thereof and without losing its phase change materials. After being heated up the heat emission of this composition is steady and consequently the composition has a long radiation time. Furthermore the polymer composition is easy to produce and has due to its special properties a lot of applications.
