Properties of polyvinyl alcohol PVA is an odorless white flake, flocculent or powdery solid. It is soluble in water, slightly soluble in dimethyl sulfoxide, but insoluble in gasoline, kerosene, vegetable oil, benzene, toluene, dichloroethane, carbon tetrachloride, acetone, ethyl acetate, methanol, et...
Hydrophilic and antibac- terial properties of polyvinyl alcohol/4-vinylpyridine graft polymer modified polypropylene non-woven fabrics membranes. Journal of Membrane Science, 345, 223-232.Wang Chanchan, Yang Fenglin, Liu Lifen, et al. Hydrophilic and antibacterial properties of polyvinyl alcohol/4- ...
Cellulose nanocrystals isolated from water hyacinth fiber (WHF) have been studied as a reinforcement for polyvinyl alcohol (PVA)-gelatin nanocomposite. Central composite design was used to study and optimize effects of the PVA, gelatin and cellulose nanocrystal (CNC) concentration on tensile strength ...
Soxhlet extraction with water, done to determine leachability of the polymer from the polymer cement paste, revealed that the percentage of polyvinyl alcohol leached out was less when borax or PF resin was added to the PVAL cement paste. The compressive strength of the poly vinyl alcohol鈥損hen...
This study investigates the effect of glass waste powder content on the UV–Vis spectroscopy of polyvinyl alcohol (PVA). The glass powder was obtained
of zirconium ions (Zr4+) with polyacrylic acid (PAA) and the Hoffmeister effect-sensitive property of polyvinyl alcohol (PVA). Meanwhile, biomimicking the environmental tolerance mechanism of spider silk, hydroxyl-rich glycerol (Gly) was introduced, the strong hydrogen bonding effect of Gly could ...

Name: Polyvinyl Alcohol English abbreviation: PVA Polyvinyl alcohol (PVA) is a white, stable, and non-toxic water-soluble polymer made by polymerization and alcoholysis of vinyl acetate, in the form of powder, flake, or flocculent solids. Polyvinyl alcohol contains many alcohol groups, has ...
As it is very difficult to obtain molecularly dispersed solutions of polyvinylalcohol (PVA) in water and as the properties of these solutions change on ageing due to the formation of aggregates, the dissolution behavior and solution properties of PVA with molar masses ranging from 15 to 690 kg...
A group of films mainly composed of sericin and poly(vinyl alcohol) (PVA), using boric acid (BA) as a modifier, were prepared by a technique of solution casting. In this work, the effect of BA and sericin on the mechanical properties and water resistance
