溶液的相对粘度测量是评定聚合物特性的传统的方法之一。可以从粘度数据得到关于聚合物结构的重要信息,例如分子量,分支度,链的刚度和链的形状,聚合物—溶剂的相互作用的性质。虽然这种方法有效,但最近几年,溶液粘度法比起其它采用先进仪器来实现高灵敏、快速和易于操作的聚合物特性表征法,已 The relative viscosity measurement of a solution is one of the traditional methods of assessing the properties of a polymer. Important information about the structure of the polymer, such as molecular weight, degree of branching, stiffness of the chains and the shape of the chains, polymer-solvent interaction properties, can be derived from the viscosity data. Although this method is effective, in recent years, the solution viscosity method has been used to characterize polymers that are more sensitive, faster and easier to handle than other advanced instruments
