Result of thermogravity analysis showed that the thermal stability of polyvinylamine chloride lowers with increasing in amination degree. Moreover, properties of dilute aqueous solutions of three types of poly chloride with different amination degree were compared by use of viscosimetric, conductometric, and potentiometric measurements. Results showed that both the electrostatic interaction of neighboring groups on the chain and the reduced viscosity of poly chloride are increased with increasing the degree of amination of poly . The equivalent conductivity is decreased with the increasing the concentration of poly chloride and increased with the increasing the amination degree of poly .
