PP/NBR共交联体冲击韧性的研究

Study of the Toughness of Crosslinked PP/NBR Blend

用过氧化二异丙苯 ( DCP)作为交联剂 ,以松节油为助交联剂对聚丙烯 ( PP) /丁腈橡胶 ( NBR)共混体系进行了化学交联 ,考察了 NBR和 DCP用量对 PP/ NBR共交联体的韧性的影响。结果表明 ,适量的 NBR和 DCP可明显改善

In this paper,the PP/NBR blends are chem-crosslinked by DCP and turpentine.And the relationships between the dosal of DCP or NBR and the toughness of PP/NBR blends are disscussed.The results show that DCP and NBR at appropriate dosal can improve the toughness of PP.
