The present invention relates to novel PMMA foams and to their production. Here, polymers, obtained by copolymerizing methacrylic amides, such as for example N-isopropyl methacrylamide, and without styrol, are foamed. It has been surprisingly found that, according to the invention a stable, simple to produce PMMA foam with very good properties, such as very high compressive strength can be obtained, which in particular, can be bound much easier to cover layers compared to known PMMA foams. |
