摘要
介绍聚酯羟值测定方法。较好的解决了测试过程中树脂状物析出的问题,测试结果稳定。精密度好。文章还对聚酯羟值的酸值修正问题进行了探讨。
The method introduced here for determining the hydroxy value in polyester satisfactorily solves the problems existing in the separation of resinous substances during the determining process. The testing result is stable and is of high precision. This paper also discusses about the modification for the acid value of hydroxy in polyster.
