摘要
采用红外光谱法测定了氯乙烯-醋酸乙烯酯共聚糊树脂中醋酸乙烯酯的含量,并与热重法、化学分析法等分析方法进行了比较。指出氯乙烯-醋酸乙烯酯共聚糊树脂中醋酸乙烯酯含量的多种测定方法各有其特点,需要根据实际情况选用;红外光谱法快速、准确,可满足企业科研和生产所需。
Infrared spectroscopy was adopted to determine the vinyl acetate content in vinyl chloridevinyl acetate copolymer paste resins, and was compared with other analytical methods, such as thermogravimetry and chemical analysis. It was indicated that various methods for the determination of vinyl acetate content in vinyl chloride-vinyl acetate copolymer paste resins had their own characteristics, and should be choosed according to actual situations ; infrared spectroscopy was ripid and accurate, and could meet the enterprises＇ requirements for scientific research and production.
