| 摘 要： | 采用酚醛树脂（PF）、DCP和硫磺等硫化体系对PA／SAN／NBR共混体系进行动态硫化，研究了该共混体系的缺口冲击强度、冲击行为和分散相形态。结果发现，PF比其它硫化体系更有效，可制得超韧的PA／SAN／NBR（50／25／25）合金；SEM照片表明，随着PF用量增加，共混体系中分散相粒子变小，形态变规则，动态硫化体系的相容性变好。

STUDY ON THE IMPACT PROPERTY OF THE DYNAMICALLY VULCANIZED PA/SAN/NBR BLENDS |
| |
| Abstract: | A series of curing agents were used to dynamically vulcanize PA/SAN/NBR blends. The effect of PF content on izod notched impact strength and morphology of the dynamically vulcanized PA/SAN/NBR (50/25/25) blends was studied. The SEM pictures showed that with increasing of PF content, the disperse-phase became more uniform and the particle size became smaller, which proved that the dynamically vulcanized PA/SAN/NBR became more compatible due to the introduction of PF compound. |
