Among other advantages, water-soluble grades of Vazo® (56 WSP, 56 WSW, and 68 WSP) offer narrow molecular weight distribution and minimal branching. They are also sulfur-free. Although used predominantly in an emulsion polymerization mechanism, water-soluble grades of Vazo® can also be used in solution polymerization.
