研究了马来酸酐接枝乙烯-辛烯共聚物(POE-g-MAH)和POE-g-MAH/聚丙烯(PP)共混物对聚对苯二甲酸丁二醇酯(PBT)的增韧作用。结果表明,POE-g-MAH/PP共混物对PBT的增韧效果优于POE-g-MAH的,POE-g-MAH和PP并用具有显著的协同增韧作用。扫描电镜照片表明,POE-g-MAH/PP共混物增韧PBT具有软壳-硬核结构。
The effects of POE-g-MAH and POE-g-MAH / PP blend on polybutylene terephthalate (PBT) Tough effect. The results showed that toughening effect of POE-g-MAH / PP blend on PBT was better than that of POE-g-MAH. POE-g-MAH and PP had significant synergistic toughening effect. Scanning electron micrographs show that POE-g-MAH / PP blends toughened PBT has a soft shell - hard core structure.
