摘　　要：硬脂酸钙是溴化丁基橡胶中的一种重要添加剂。本文采用傅里叶变换红外光谱法,分别通过热压成膜和溶液成膜的样品制备方式,建立了测定溴化丁基橡胶中硬脂酸钙含量的方法。对两种样品制备方法进行了比较。结果表明,两种方法都有较高的准确度。热压成膜法制样简单适于工业样品的质量控制,溶液成膜法适于硬脂酸钙含量较高的样品。Calcium stearate is an important additive in brominated isobutyleneisoprene rubber（BIIR）.A FTIR method for the determination of calcium stearate content in BIIR was established.The sample films were prepared by hot-pressing and solution methods,respectively,and two methods were compared.Experimental results of both sample preparation methods are accurate.However,the hot-pressing technique is simple and appropriate for quality control of industrial products,while solution method is appropriate for samples with higher concen tration of calcium stearate.
