본 발명은 신규한 PMMA 발포체 및 이의 제조에 관한 것이다. 이러한 경우에, 제조에 사용된 제형은, 제형의 구성성분으로서 적합한 발포제 이외에 특히 및 대부분 낮은 농도의 가교제 및 조절제를 포함한다. 놀랍게도, 본 발명에 따라, 매우 양호한 특성을 갖는, 안정하고 제조가 간단한 PMMA 발포체를 수득할 수 있다는 것이 발견되었다. The present invention relates to novel types of PMMA foams and also to the production thereof. The recipes used in the production process include particularly crosslinkers and chain transfer agents as recipe constituents, mostly in low concentrations, in addition to suitable blowing agents. It was found that, surprisingly, the invention provides a simple-to-produce stable PMMA foam having very good properties.
