摘要
利用ATR技术测量样品的红外光谱,采用偏最小二乘法对所测光谱进行分析,建立了一种快速分析方法;对乙烯-乙酸乙烯酯共聚物中乙酸乙烯酯进行测定。结果表明:标准曲线线性关系良好,相关系数为0.99985,方法简单快速,结果可靠。
IR spectra of ethylene/vinyl acetate copolymer （EVA） were measured using ATR technique, and then were analyzed using partial least square method. Therefore, a method was established to determine the vinyl acetate （VAC） mass fractions in EVA. The results showed that the standard sample curves are very good in linearity with a correlation coefficient of 0. 99985. The established method was simple, rapid, reliable and suitable for the determination of VAC mass fractions in EVA.
