Poly(vinyl alcohol), MW 25000, 98% hydrolyzed
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.
