The National Bureau of Standards has issued a series of three linear polyethylene Standard Reference Materials, SRM 1482, 1483, and 1484. These polyethylenes have molecular weights of the order of 10,000, 30,000, and 100,000 g/mol, respectively, and ratios / of weight- to number-average molecular weight of the order of 1.2. Their number-average molecular weights (by membrane osmometry), weight-average molecular weights (by light scattering), and limiting; viscosity numbers in two solvents (by capillary viscometry) are certified; the procedures employed are described in subsequent papers in this series. In the present paper, we describe the preparation of the materials and some of their general properties.
美国国家标准局已发布了一系列三种线性聚乙烯标准参考物质，即标准参考物质1482、1483和1484。这些聚乙烯的分子量分别约为10,000、30,000和100,000 g/mol，重均分子量与数均分子量之比约为1.2。它们的数均分子量（通过膜渗透压法测定）、重均分子量（通过光散射法测定）以及在两种溶剂中的特性粘数（通过毛细管粘度法测定）均已得到认证；本系列后续论文中描述了所采用的程序。在本文中，我们描述了这些物质的制备方法及其一些一般性质。
