ABSTRACT:
A method of determining sulfur loading of an organic polysulfide composition comprises reacting the organic polysulfide composition with an organic phosphine to produce reaction products comprising organic phosphine sulfide and an organic sulfide selected from the group consisting of organic disulfide, organic trisulfide and mixtures thereof; and analyzing the reaction products by gas chromatography to determine the amount of sulfur.
