Poly(vinyl alcohol), MW 133000, 99% hydrolyzed (PVA 133K 99%)
Polyvinyl alcohol (PVA, PVOH) is a 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.
