| Abstract: | A laser light scattering method to determine molecular weight and its distribution of a novel bonding agent BAG is introduced and experimental principle and procedure are given in the paper. The method takes dilute solution of KBr in N,N-dimethylformamide as mobile phase and solvent, and gel permeation chromatographic column as separation system. The results show that accuracy and precision of the method is satisfactory. It can be used as a routine method to determine BAG molecular weight and its distribution. |
