Standard Test Method for Polyurethane Raw Materials: Determination of Unsaturation of Polyols

Importancia y uso:

5.1 This test method is suitable for quality control, as specification tests, and for research.

5.2 Side reactions that form unsaturated compounds in polypropylene oxides produce small amounts of polymers with only one hydroxyl group per chain. These unsaturated polymers lower functionality and molecular weight, while broadening the overall molecular-weight distribution.
