本文介绍了一种利用裂解色谱测定氯甲基化聚苯乙烯含氯量的方法。该法快速、方便、结果可靠。实验表明,氯甲基化聚苯乙烯裂解产物中乙烯基甲苯峰高百分数的对数与样品含氯量呈线性关系,籍以可测定样品含氯量。
This article describes a method for the determination of chloromethylated polystyrene with chlorine by pyrolysis chromatography. The method is fast, convenient and reliable. The experimental results show that the logarithm of the percentage of peak height of vinyl toluene in the chloromethylated polystyrene cracking product is linear with the chlorine content of the sample, so that the chlorine content in the sample can be determined.
