Acrylonitrile-butadiene rubber /polyethylene oxide(NBR/PEO) blends were prepared by solution-casting method,and the effect of interaction between NBR and PEO on the crystalline behavior was investigated by contact-angle testing,Fourier transform infrared spectroscopy and differential scanning calorimetry.The results showed that the interfacial energy and work of adhesion of NBR/PEO blends were 8.80 mJ/m2and 56.90 mJ/m2respectively,there was a certain compatibility between the two.There was no interaction between —CN and ether group,so that the certain compatibility was contributed by the non-polar part of them.As the PEO content decreased,the gauche conformation of molecular chain in the PEO crystal structure increased moderately,as well as the crystallinity and crystalline melting temperature of PEO decreased evidently.While the PEO amount was 5 phr,PEO crystallinity and crystalline melting temperature were reduced by 80% and 10.5 ℃ in NBR/PEO blends system separately,showing a good inhibiting effect of NBR on PEO crystallinity.
