본 발명은 신규한, 미세-포어 PMMA 발포체 및 이의 제조에 관한 것이다. 제조에 사용된 제형은 적합한 발포제 이외에 조핵제를 포함한다. 예상 외로, 매우 미세한 포어 및 매우 양호한 특성을 갖는, 안정하고, 제조가 간단한 PMMA 발포체가 본 발명에 따라 수득될 수 있다. Fine-cell PMMA foams are produced using a production process including nucleators in addition to suitable blowing agents. It was found that, surprisingly, a simple-to-produce stable PMMA foam having very fine cells and very good properties can be produced.
