【摘要】 硼酚醛树脂是一种耐热性极佳的聚合物，但其存在脆性大、易断裂的缺陷。通过引入端羧基丁腈橡胶对硼酚醛树脂进行增韧改性，显著改善了硼酚醛树脂的力学性能。通过傅里叶变换红外光谱对端羧基丁腈橡胶与硼酚醛树脂的反应原理进行了分析，明确了羧基丁腈橡胶与硼酚醛树脂的主要反应过程，为后续的相关研究提供了一定的理论基础。更多还原

【Abstract】 Boron phenolic resin is a kind of polymer with both excellent thermostability and high brittleness. Carboxyl terminated nitrile rubber was introduced to toughen boron phenolic resin, the result shows that the mechanical properties of boron phenolic resin was significantly improved. In this study, the reaction principle of carboxyl terminated nitrile rubber and boron phenolic resin was analyzed by FTIR, the reaction process of carboxyl terminated nitrile rubber and boron phenolic resin was also clarified, which provided a certain theoretical basis for subsequent related research.更多还原
