ASTM WK68732
It has been studied that mercaptans and disulfides in styrene monomer negatively affect the downstream polymerization of Styrene. Adversely, Thiophenic sulfur is not harmful to the styrene polymerization process. Therefore, there needs to be a standard method which determines the two types of sulfur in Styrene monomer (thiophenic and non-thiophenic). Furthermore, Styrene monomer specification (ASTM D2827) may change in the future to reflect non-thiophenic sulfur limitation. Thus, this method can be used for the determination of the non-thiophenic sulfur in Styrene as will be specified in the new ASTM D2827.
