The present invention relates to innovative PMMA foams and their production. herein, polymers that have been obtained by copolymerization of methacrylamides as n-isopropyl methacrylamide and without styrene are foamed. It has been surprisingly possible to establish that a stable, simple-to-produce pmma foam that has very good properties, for example very high compressive strength, and can be joined more simply to cover layers, especially compared to known pmma foams, can be used. obtained according to the invention. |
