PVA (Mw 67000, 87-89% hydrolyzed, ~1400 polymerization)  (Synonyms: Polyvinyl alcohol (Mw 67000, 87-89% hydrolyzed, ~1400 polymerization); Poly(Ethenol) (Mw 67000, 87-89% hydrolyzed, ~1400 polymerization))

PVA (Mw 67000, 87-89% hydrolyzed, ~1400 polymerization) is a polyvinyl alcohol with a molecular weight of 67000 and hydrolytic properties. Degree of hydrolysis refers to the conversion rate of acetate groups in the original polyvinyl acetate to hydroxyl groups; PVA (Mw 67000, 87-89% hydrolyzed, ~1400 polymerization) is obtained by hydrolyzing and removing acetate groups after the polymerization of vinyl acetate. Polyvinyl alcohol with different degrees of hydrolysis can be used to form self-crosslinked cryogels and is applied as a biological adjuvant^[1].

PVA (Mw 67000, 87-89% hydrolyzed, ~1400 polymerization) (5 wt%; 3 h stability incubation) coated, 0.1 vol% GA crosslinked PVDF hollow fiber membrane achieves a water vapor permeability of 2890 Barrer and a water vapor-to-nitrogen selectivity of 289 at 25 °C, with stable performance after 3 h incubation in 90 °C water^[1].
PVA (Mw 67000, 87-89% hydrolyzed, ~1400 polymerization) (5 wt%) aqueous solution forms a 1.75 μm thick, uniformly adherent coating on PVDF hollow fibers via dip-coating at 1 m/min, with coating thickness matching LLD law predictions^[1].
