    Description / Table of Contents: Die radikalische Polymerisation von Acrylnitril in Gegonwart verschiedener ungesättigter optischer Aufheller (FB) (Derivate des 1,3,5-Triazins) wurde untersucht. Kolorimetrische Messungen ergaben, daß mehr als 80% des optischen Aufhellers in die Polymerkette eingebaut werden. Zur Erzielung eines intensiven optischen Effektes genügt eine FB-Anfangskonzentration von 0,1 Gew.-%, bezogen auf Acrylnitril.
    Notes: The polymerization of acrylonitrile in the presence of some unsaturated, triazinebased fluorescent brighteners (FB) has been investigated. It was found colourimetrically that more than 80% of the FB is incorporated in the polymer. The initial concentration of 0.1 wt.-% is sufficient to obtain a good bleaching effect without significant decrease of the molecular weight.
