Molecular formula :
nature : polymer chain said contained the weight of the number of structural units. The general said the average degree of polymerization, largely because of different polymer molecular weight of the mixture with the department. For example, cellulose is the Molecular Formula (C6H10O5) n, n is the poly adaptation (also available as indicated x). General Polymer greater degree of polymerization, the polymer has greater tensile strength. As calculated by the number-average molecular weight, molecular weight and viscosity-average molecular weight of different, there were few degree of polymerization (number-average DP), the weight-average degree of polymerization (weight average DP) and the viscosity average degree of polymerization (DP viscometric) distinction.
