| Abstract: | This paper studies the effects of conversion, polymerization temperature, nature and concentration of chain transfer agents on the average molecular weight of poly (vinyl chloride), and proposes a regulation model of the average molecular weight of PVC.
The model may be used to estimate the average molecular weight of PVC in the polymerization process with mercaptoethanol or trichloroethylene as chain transfer agent. |
