摘要
评定了酰化法测定端羟基聚丁二烯羟值的测量不确定度。分析了测量重复性、称量过程及标准物质稳定性等因素所带来的不确定度分量,采用酰化法测定端羟基聚丁二烯羟值的扩展不确定度为0.01mmoL/g。
The uncertainty of measurement in the determination of the hydroxyl value of hydroxyl-terminated polybutadiene by
acylation was evaluated. The components of the uncertainty of measurement caused by the repeatability of measurement, the weighing process, the stability of certified reference material and so on were analyzed. The expanded uncertainty of the hydroxyl value of hydroxyl-terminated polybutadiene determined by acylationis is 0.01 mmol/g.
