Novolac cyanate ester–polyhedral oligomeric silsesquioxane (POSS, MA0735) copolymers were prepared by adding different amounts of MA0735 into novolac cyanate ester resin. The curing behaviors and properties of these polymers were analyzed and compared by thermogravimetric analysis (TGA), dynamic mechanical analysis (DMA), Fourier-transform far infrared spectroscopy (FTIR), and simple beam impact testing machine. The results showed that the comprehensive properties of the polymer with 0.5% MA0735 were optimal. The addition of a small amount of MA0735 can yield both heat resistance and impact toughness.

酚醛氰酸酯-多面体低聚倍半硅氧烷共聚物的固化行为和热机械性能
通过将不同量的 MA0735 添加到酚醛氰酸酯树脂中，制备了酚醛氰酸酯 - 多面体低聚倍半硅氧烷（POSS，MA0735）共聚物。通过热重分析(TGA)、动态力学分析(DMA)、傅里叶变换远红外光谱 (FTIR) 和简单的光束冲击试验机对这些聚合物的固化行为和性能进行了分析和比较。结果表明，0.5%MA0735聚合物的综合性能最佳。添加少量 MA0735 可同时产生耐热性和冲击韧性。
