Abstract
The invention relates to compounds for producing polymethacrylimide foam materials (PMI foams) with particularly good mechanical properties, in particular with a particularly advantageous elongation at tear. The invention further relates to methods for producing, processing, and using said foam materials. In particular, the invention relates to novel materials, the propensity of which to form tears is clearly reduced in comparison to the prior art. This is tantamount to an elongation at tear that is higher in comparison to the prior art.
