摘要
本文介绍了用红外光谱法测定羧基丁苯胶乳中结合苯乙烯含量的方法，通过该方法分别选择１４９５ｃｍ^（－１）作为苯乙烯的芳烃Ｃ＝Ｃ伸缩振动特征吸收带和９７０ｃｍ^（－１）作为丁二烯的反式Ｃ＝Ｃ非平面摇摆振动特征吸收带。结果求得直线回归方程，相关系数，相对标准偏差，精度范围等。本方法简单、快速、选择生强，已成功地应用于羧基丁苯胶乳中结合苯乙烯含量的测定。
This paper described a method on the determination of bound styrene content in the carboxylated styrene butadiene rubber latex by IR spectrometry. By this, characteristic absorption band in that rubber latex at 1495cm(-1) is chosen as the aryl C =C stretching vibration of stWene, and that at 970cm(-1) as the trans C=C wagging vibration of butadiene respectively. Consequently regression equation of calibration curve, coefficent of correlation, relative standard deviation, attainable precision are obtained. It is simple, speed, highly selective method and it has already been satisfactorily appling to the determination of bound styrene content in the carboxylated styrene butadiene rubber latex.
