where GL is graft level (in mass %), MSt is molar mass of styrene (104.2 g/mol), MAN is molar mass of acrylonitrile (53.1 g/mol), MStSA is molar mass of styrene sulfonic acid (184.2 g/ mol), XSt is the molar fraction of styrene in grafts, XAN is the molar fraction of acrylonitrile in grafts, and XAN = 1 − XSt. The results reported and conclusions of the work are not affected by the correction.
