注解： MnNumber average molecular weight MpPeak average molecular weight MvViscosity average molecular weight MwWeight average molecular weight MzZ-average molecular weight IV*Intrinsic Viscosity (dl/gm) 数均分子量（Number-average molecular weight）：按聚合物中含有的分子数目统计平均的分子量，高分子样品中所有分子的总重量除以其分子(摩尔)总数。 重均分子量（Weight-average molecular weight）：按照聚合物的重量进行统计平均的分子量，i-聚体的分子量乘以其重量分数的加和。 Z均分子量（Z-average molecular weight ）：按照Z值统计平均的分子量 粘均分子量（Viscosity- average molecular weight）：对于一定的聚合物－溶剂体系，其特性粘数[η]不同。 Mz > Mw > Mv > Mn，Mv略低于Mw Mn靠近聚合物中低分子量的部分，即低分子量部分对Mn影响较大 Mw靠近聚合物中高分子量的部分，即高分子量部分对Mw影响较大 一般用Mw来表征聚合物比Mn更恰当，因为聚合物的性能如强度、熔体粘度更多地依赖于样品中较大的分子。 上海西宝生物科技有限公司提供美国聚合物标准品公司（APSC）的进口原装聚合物标准品，价格实惠，服务周到。主要分为有机凝胶色谱标准品（Organic GPC/SEC Standards）和水性凝胶色谱标准品（Aqueous GPC/SEC Standards）两类。 更多相关产品，欢迎咨询： 上海西宝生物科技有限公司 电 话：021-502729 75/76/77/78-6221/6512/6236 杨露13512172575 QQ:1916572322分机6221
