摘    要:用红外光谱(IR)研究氢化NBR—230型丁腈胶中发现,724cm-1和2236cm-1特征吸收带的相对吸光度(A1)随着丁腈胶加氢程度(饱和度=H)的增加而增大,970Cm-1和2236cm-1特征吸收带的相对吸光度(A2)随着氢化丁腈胶饱和度的增加而减小。在饱和度为70%~90%的范围内,A1值与H值呈线性关系,在饱和度≤70%范围内,A2值与H值呈线性关系,从而建立了用IR光谱法测定丁腈胶饱和度的方法。

关 键 词:饱和度 红外光谱 氢化 丁腈橡胶 橡胶

Abstract:The hydrogenated nitrile rubber NBR-230 has been studied by IR method.we find that with the increasing of the degree of hydrogenation,the ratio A(724cm-1 )/A(2236cm-1)=A,increases while the ratio A(970cm-1)/A(2236cm-1)=A2 reduces.In this paper,the proportionality relations between the degrees of hydrogenation and the values of A,or A1 are considered.As a conclusion,we put up a method which can determine the degree of hydrogenation by IR spectrometry instead of iodometry.
Keywords:nitrile rubber(NBR)  degree of hydrogenation  infrared(IR)spectrometry
