Quality Standard: CHP 2020; USP43-NF38; EP10.0; GB31630-2014

Features:

Prepared by alcoholysis of polyvinyl acetate in methanol solution by adding alkali solution.

The M. F. is (CH2CHOH) n (CH2CHOCOCH3) m, where ‘m + n’ represents the average degree of polymerization, and m/n should be 0~0.35. The average M. W. shall be 20000 ~ 220000.

There are many types of polyvinyl alcohol according to the degree of polymerization and alcoholysis. The naming rule is "polyvinyl alcohol xy-mn", where xy represents average degree of polymerization and mn represents degree of alcoholysis.

Our company mainly produces models with alcoholysis degree of 88%, including 03-88, 05-88, 17-88, 24-88, 50-88 models, and other models can be customized if necessary.
