摘要
本文综述了聚甲基丙烯酰亚胺（PMI）泡沫塑料的制备方法以及结构和性能，PMI由于具有良好的力学性能、热变形温度和化学稳定性，是高性能夹层结构复合材料的理想芯层材料。针对目前国外PMI的研发现状，介绍了一些调变PMI性能和改进制备工艺的方法，希望对国内PMI的研究起到借鉴的作用，最后对PMI的应用做了简单的介绍。
The preparation, structure and performance of polymethacrylimide （PMI） foam plastics were summarized in this article. PMI is an ideal core material for the high-performance sandwich composite materials because of its good mechanics performance, heat distortion temperature and chemical stability. In view of the present research and development situation of PMI, the ways to modify the performance and preparation of PMI were introduced with hope to use them for reference. And the applications of PMl were also introduced.
