相容剂对CR/PVC热塑性弹性体的相容作用

研究了相容剂NBR和Elvaloy 741对CR/PVC共混物(共混比70/30)性能的影响，并通过透射电镜和红外光谱表征了相容剂NBR和Elvaloy 741对CR/PVC共混物的相容效果。结果表明，相容剂Elvaloy 741与CR和PVC之间有较强的相互作用，相容剂NBR和Elvaloy 741加入CR/PVC共混物中，使分散相尺寸变小；当相容剂用量为CR/PVC共混物中PVC用量的10%时，共混物具有较好的综合性能。;The influences of the compatibilizers NBR and Elvaloy 741 on the properties of CR/PVC(70/30) blend were studied，and their compatibilizing effects were characterized by TEM and IR spectrum.The results showed that the compatibilizer Elvaloy 741 interacted strongly both with CR and PVC，and the size of discontinuous phase was decreased by adding the compatibilizers NBR and Elvaloy 741 to CR/PVC blend；the better comprehensive properties of CR/PVC blend were obtained when the compatibilizers NBR and Elvaloy 741 accounted for 10% of PVC by weight
