Polyvinyl alcohol (PVA, PVOH) are water-soluble resins of low toxicity. Resins at high % hydrolysis require heating at ~96°C in water for solution. Resins of lower % hydrolysis can be dissolved at progressively lower temperatures with 88% hydrolyzed resin requiring only 85°C for solution.
Soluble in: hot glycerol, hot glycols, hot water.88 mol% hydrolyzed polyvinyl acetate (PVAc) Polydispersity ~2.0
