相对分子量平均分子式：CAS号：性质：又称相对分子量平均（relative moleculat-mass average），分子量平均(molecular-weight average)。是多分散聚合物的摩尔质量或相对分子质量（分子量）的任一平均。物质的摩尔质量（分子量）和相对摩尔质量（相对分子量）在数值上是相等的。聚合物科学中，摩尔质量的单位推荐使用g/mol，相对摩尔质量是纯数字，与任何单位无关。商品聚合物一般是聚合度或分子量不同的同系物分子的混合物，分子量大小及分布的宽窄与聚合物的物理力学性能、加工性能有密切关系。分子量分布遵循统计原理，得到的分子量分布与分析有关，必须注明所用方法。通常使用数均、重均和黏均三种摩尔质量平均。
