Beschreibung
Zusammenfassung:	The invention relates to a method for producing low density, polyolefin foamed article, comprising: Forming a solution of a polyolefin in a first solvent at a temperature above the dissolution temperature, Shaping the solution to a 3-dimensional solvent containing article, Converting the solvent containing article into a gel article by cooling the article to below the gelation temperature of the solution, Supercritical extraction of the solvent from the gel article with a supercritical fluid, as well as to a polyolefin foamed article, comprising nanotubes.
