Fund Project: This work was supported by the National Natural Science Foundation of China and Polymer Physics Laboratory, Institute of Chemistry, Academia Sinica, Beijing China.

The effects of the nature of salts,salt concentration,pH value,degree of hydrolysis as well as surfactant on molecular size of HPAM were studied.It is found that [η] of HPAM changes with all the above variables,and the molecular weight of HPAM can be obtained through [η] measurement at a specific salts environment in which the [η] is independent of above factors.
