本标准规定了溶液聚合物分子量(用聚苯乙烯表示)及其分子量分布的测定方法。
本标准适用于可完全溶解于四氢呋喃的、分子量范围为5×103~1×106的溶液聚合物。
Scope
Warning: Personnel using this standard should have practical experience in formal laboratory work. This standard does not address all possible safety issues. Users are responsible for taking appropriate safety and health measures and ensuring compliance with the conditions stipulated in relevant national regulations. This standard specifies the method for determination of solution polymer molecular weight (expressed in polystyrene) and its molecular weight distribution. This standard applies to solution polymers with molecular weights ranging from 5×10 to 1×10 that are completely soluble in tetrahydrofuran (THF).
