Linear polyethylene Standard Reference Materials SRM 1482, 1483, and 1484 are certified for limiting viscosity number in 1,2,4-trichlorobenzene and 1-chloronaphthalene at 130 °C. In this paper the experimental procedures employed for the determination of limiting viscosity numbers for these materials by capillary viscometry are described, and the techniques used to analyze the data and to estimate limits of systematic error are discussed.
线性聚乙烯标准参考物质SRM 1482、1483和1484经认证,其在130℃下于1,2,4-三氯苯和1-氯萘中的特性黏数有规定值。本文描述了采用毛细管黏度计测定这些物质特性黏数的实验步骤,并讨论了用于分析数据和估计系统误差限度的技术。
