摘要: 在氰酸酯树脂(CE)中加入端羟基聚丁二烯橡胶(HTPB)以改善其韧性。利用傅单叶红外光谱(FT-IR),热综合分析仪、原子力显微镜(AFM)等方法研究体系的反应性,测宗其力学性能,耐热性等性能。实验结果表明,HTPB的加入很奸地改善了CE的韧性,当HTPB含量沐到25%时,体系的冲击强度捍高最大,接近19 kJ/m2,并且_保持了树脂良好的耐热性能

Abstract: Cyanatc ester resin (CE) was modified by hydroxyl-terminated polybutadicnc(HTPB>.The reactivity between the components and the properties of the system were studied using Fouricr transform infrared spectroscopy(FT-IR >,DSC-TG, atomic force microscope(AFM).It showed that the flexibility of the blends was increased without a loss in the thermal stability. When the content of HTPB is 25%,the impact strength of the blends was close to 19 kJ/m2.

Key words: cyanatc ester resin, hydroxyl-terminated polybutadicnc, toughening, amide
