The interaction between carbon black N234 and the rubber was studied by infrared spectroscopy(IR). The red shift(shift to low wavenumber) of group characteristic peak of the rubber with different dosages of carbon black N234 was observed. The results showed that with the addition of carbon black N234,the IR characteristic peaks of natural rubber(NR),solution polymerized styrene-butadiene rubber(SSBR),emulsion polymerized styrene butadiene rubber(ESBR) and butadiene rubber(BR) all presented a red shift in different degrees. Due to the strong interaction between carbon black N234 and NR,the red shift degree of methylene group characteristic peak of NR was the largest. With the increase of carbon black N234 amount,the red shift degrees of different group characteristic peaks of rubber were different,and the interaction between different groups of rubber and carbon black N234 was different. The red shift degree was not affected by the blending of rubbers. With the addition of carbon black N234,the red shift results of group characteristic peaks of the vulcanized blends were the same as the unvulcanized ones.
