本标准规定了聚氯乙烯(PVC)树脂比浓黏度(也称黏数)和K值的测定条件,适用于氯乙烯均聚物及由氯乙烯同一个或更多其他单体构成(但其中主要成分为氯乙烯)的二共聚物和三共聚物等粉末型树脂。树脂可以含有少量的非聚合物质(例如,乳化剂或分散剂、残留引发剂等)和在聚合过程中填加的其他物质。但是,本标准不适用于根据GB/T 2914进行测定挥发物含量超过0.5%的树脂以及不能完全溶解在环己酮中的树脂。一个特定树脂的比浓黏度和K值与它的相对分子质量相关 但是关系变化依赖于所存在的其他单体的浓度和类型。因此具有相同的比浓黏度或K值的均聚物和共聚物的相对分子质量也可能不同。对于一个特定的PVC树脂样品 所选择的测定溶液的浓度对用于确定比浓黏度或K值的数值有不同的影响。因此 只有当所用的溶液浓度相同时,按本标准描述的步骤所得出的比浓黏度和K值才可以进行比较。
