Abstract: The invention relates to a process for production of expanded thermoplastic elastomer, said process comprising the steps of: (e) adding monomers and/or oligomers used for producing the thermoplastic elastomer with or without further starting materials into a first stage of a polymer-processing machine, (f) mixing the monomers and/or oligomers and also the optionally added further starting materials and reacting the monomers and/or oligomers to give a polymer melt in the first stage of the polymer-processing machine, (g) passing the polymer melt into a second stage of a polymer-processing machine and adding a physical blowing agent with or without further starting materials to obtain a polymer melt comprising a blowing agent, (h) molding the polymer melt comprising a blowing agent into an expanded thermoplastic elastomer.
