I. Grabchev et T. Philipova, Polymerization of styrene in the presence of some triazine-stilbene fluorescent brighteners, ANGEW MAKRO, 263, 1998, pp. 1-4
The radical polymerization of styrene in the presence of six fluorescent br
ighteners (FB), derivatives of 4,4'-bis(1,3,5-triazin-2-ylamino)-stilbene-2
,2-disulfonic acid comprising polymerizable groups, has been studied. By me
ans of UV-Vis and FT-IR spectroscopy it was found that the fluorescent brig
hteners are covalently bound to the polymer chain. The introduction of fluo
rescent brighteners into the polymer chain results in polystyrene with fluo
rescent properties.
