摘要
采用丁腈橡胶（ＮＢＲ）及其氢化还原后产物（ＨＮＢＲ）为ＰＶＣ／ＨＤＰＥ共混体系的增容剂，研究了增容剂结构、用量及丙烯腈含量对共混体系相容性的影响。发现丁腈橡胶（ＮＢＲ２９及ＨＮＢＲ２９）对ＰＶＣ／ＨＤＰＥ体系有较好的增容作用，而ＮＢＲ４０及ＨＮＢＲ４０较差。当增容剂用量为２％，ＰＥ含量为８％～１２％时，共混物具有较好的相容性，力学性能得到改善。
This paper used NBR and hydrogenated NBR(HNBR) as the compatibilizer of PVC/PE blends,and studied the effects of the structure of copolymer, the amount of HDPE, copolymer and AN on the compatibility of blends.It had been found that NBR 29 and HNBR 29 were better for compatibilizing PVC/HDPE blends,but NBR 40 and HNBR 40 not. When the PVC/HDPE blends contained 2% compatibilizers,they show the good compatibility and mechanical properties.
