Disciplinarian analysis on factors affecting PVA average degree of polymerization

In order to master the waving discipline of PVA average degree of polymerization,the effects of reation temperature,time and amount of methanol and solicitation on PVA average degree of polymerization were studied in this paper through the single factor methoel.The average degree of polymerization increases with the increase of the amount of methanol and solicitation,and it increases at the beginning but some time later decreases with time.
