The present invention relates to novel PMMA foams and also to their preparation. Here, the polymer obtained by copolymerization of methacrylamide such as N-isopropyl methacrylamide without styrene is foamed. Surprisingly, it has been established that a stable and simple to prepare PMMA foam, which has very good properties such as very high compressive strength, and which can be more simply bonded to the coating layer, in particular compared to known PMMA foams, can be obtained according to the invention . |
