POLYSULFIDE MEASUREMENT METHODS USING COLORIMETRIC TECHNIQUES

摘要

Methods of converting a sulfide in a composition to polysulfide are described, one method comprising the steps of exposing the composition to conditions and for a time sufficient to cause conversation of at least a portion of the sulfide, to polysulfide to form a modified composition; and controlling the conversation to polysulfide by measuring a color parameter of the modified composition.
