摘要
介绍了在高温条件下测定聚酯羧基的方法,以苯甲醇为溶剂溶解样品,测定结果的标准偏差在0.26%-0.48%之间。同时与用CB/T14189测定聚酯羧基的方法测定结果相比较,两种方法测得的结果是平行的,试验结果表明该方法快速、准确,具有实际应用价值。
The acid - base titration technique about determination of polyester carboxyl was introduced in this paper. Benzyl alcohol solved sample .The standard deviation of method was between 0.26 % and 0.48 %. At the same time compareing the method with GB/ T14189- 93 "The method about determination of polyester carboxyl", Parallel result have been obtain from the two methods. Which showed that the method presented in this paper was proved to be accurate,rapid and practical.
