This paper discussed the feasibility of alternating the sequences of charging traditional main dispersing agents in the isothermal water charging process for the production of PVC by 70 m3 polymerizer,the influences arising therefrom on the stability of system,and the desired beneficial changes for PVC resins in properties,such as adsorption amount of plasticizer.

To solve the surface deterring technology problem of azide nitramine gun propellant (DA propellant) with high plasticizer concentration,we originally introduced 1,3-dipolar cycloaddition into deterring system.
