Polyvinyl alcohols (PVA, PVOH) are water-soluble resins of low toxicity. The water solubility primarily depends upon degree of hydrolysis of polyvinyl acetate. 88% hydrolyzed product have high degree of solubility, even in cold water, but for the complete dissolution heating to 85°C is required. Higher hydrolysis grade products require progressively more energy to dissolve because of their greater degree of crystallinity. For complete dissolution, these grades require heating to ~95°C.
88 mol% hydrolyzedPolydispersity ~1.9
Soluble in: DMSO, acetamide, glycols, DMF and water.
