一、高聚物分子量的意义合成高聚物是单体分子经过加聚或缩聚作用产生的,从聚合作用的过程来看,很难想像在一次作用所生成的产物中,高聚分子有均一的聚合度。就是天然的高分子,除几种蛋白质以外,分子量也都是不均一的。所以一个高聚物试样,有它的分子量分布,应该用分子量分布曲线来表示这高聚物的聚合情况。但是分子量分布曲线的测定,目前还是很困难的工作。在高分子化学中,所谓高聚物的分子量,只有统计的意义,就是说是一种统计的平均分子量。由于统计方法的不同,就可以有许多种不同 First, the significance of the molecular weight of polymer Synthesis of polymer is the monomer after polymerization or polycondensation effect, from the polymerization process point of view, it is difficult to imagine a role in the resulting product, the polymer molecules are uniform Degree of polymerization. Is a natural polymer, in addition to several proteins, the molecular weight is not uniform. Therefore, a polymer sample, it has its molecular weight distribution, the molecular weight distribution curve should be used to indicate the polymerization of this polymer. However, the determination of the molecular weight distribution curve is still a very difficult task. In polymer chemistry, the so-called molecular weight of polymers, only statistical significance, that is a statistical mean molecular weight. Due to the different statistical methods, there can be many differences
