Abstract

In present work we try to detect changes on styrene-divinilbenzene microporous polymer surface by
adsorption energy distribution function (heterogeneity function, χ). Polymer surface was modified by
0.1 – 104 ppm of polyethylene glycol, polyethylene glycol adipate and tripropionitrilamine. Heterogeneity
function was calculated from the inverse gas chromatography data. It is determined that function χ is capable
to detect surface properties variations only at 103 ppm and above modifier impregnation. If one use the first
derivative of χ, it allows detecting surface properties changes after 0.1-1 ppm modifier impregnation.
