“…During the last 25 years, different functional dyes have been synthesized and applied 3–5. In this direction, we have reported the synthesis and application of some reactive dyes for textiles6, 7 and monomer dyes for polymers 8–10. Among them, the fluorescent dyes are of special interest because of their pure color and intense fluorescence.…”

Six new fluorescent derivatives of 1,8-naphthalimide were synthesized. Three were dyes, and three were fluorescent whitening agents (FWAs) containing a tetramethylpiperidine (TMP) stabilizer fragment. The FWAs were obtained under phase-transfer catalysis conditions. Five of the compounds were copolymerized with methyl methacrylate, so copolymers with an intense color and/or fluorescence stable against solvents were obtained. The chemical bonding of the synthesized monomers in the polymers was confirmed spectrophotometrically. The participation of the monomer compounds did not significantly affect the process of copolymerization or the molecular masses of the obtained copolymers. The quantity of chemically bonded naphthalimide monomer in the copolymers was determined to be over 60%. The spectral properties of the compounds and their photostability in solution and in the copolymers were studied. The influence of the compounds on the photostability of the copolymers was determined. The compounds, especially those containing a stabilizer (TMP) fragment in their molecules, showed a positive stabilizing effect on the photodegradation of poly(methyl methacrylate). Polyamide fabrics with 2-allyl-6-hydrazino-benzo [de]isoquinoline-1,3-dione, 2-allyl-6-(2-aminoethylamino)-benzo [de]isoquinoline-1,3-dione, andisoquinoline-6-yl) acetohydrazide were dyed, and materials with an intense yellow color and fluorescence were obtained. Cotton fabrics were whitened with 2-(2,2,6,6-tetramethyl-piperidin-4-yl)-6-methoxy-benzo[de]isoquinoline-1,3-dione, 2-(2,2,6,6-tetramethyl-piperidin-4-yl)-6-allyloxybenzo [de]isoquinoline-1, 3-dione, and 2-[2-(2,2,6,6-tetramethyl-piperidin-4-yl)-1,3-dioxo-2,3-dihidro-1H benzo [de]isoquinoline-6-oxy]ethyl-2-methacrylate, and materials with bright whiteness and intense bluish fluorescence were obtained.

Es wurde die Polymerisation von Styrol in Gegenwart des Farbstoffs 2‐(2′‐Brom‐4′‐anilin‐1′‐anthrachinonylamino)‐4‐butyloxy‐6‐allylamino‐1,3,5‐triazin untersucht. Mit der ungesättigten Gruppe beteiligt sich der Farbstoff an der Polymerisation, wobei ein gefärbtes Polystyrol entsteht. Da der Farbstoff einen Teil der Polymerkette darstellt, behält letzteres seine Farbe auch nach mehrmaliger Umfällung. Eine intensive Färbung kann mit sehr kleinen Farbstoffmengen (0,1 bis 0,4 Gew.‐%) erhalten werden. Es wurde der Einfluß der Temperatur und der Farbstoffkonzentration auf den Prozeß untersucht. Festgestellt wurde, daß die Beteiligung des Farbstoffs an der Polymerisation einen gewissen Einfluß auf das Molekulargewicht des erhaltenen Polymeren ausübt, ohne die Polydispersität und Schmelztemperatur des Polymeren sowie die Aktivierungsenergie des Prozesses zu beeinflussen. Die vorgeschlagene Methode kann zur Herstellung von dauernd gefärbtem Polystyrol angewendet werden.

ZUSAMMENFASSUNG:Es wurde die Polymerisation von Styrol in Gegenwart einiger Farbanthrachinonund Azoderivate des 1,3,5-Triazins, die eine polymerisationsfahige Gruppe enthalten, untersucht. Die Abhangigkeit der Polymerisationsgeschwindigkeit des Styrols sowohl vom Charakter des Farbstoffs als auch von der Art der darin enthaltenen polymerisationsaktiven Doppelbindung wurde ermittelt. In den UV-und den sichtbaren Spektren der enthaltenen Farbpolymeren wurden Absorptionsmaxima beobachtet, die charakteristisch fur die Farbstoffe sind und im farblosen Polystyrol fehlen, was darauf hinweist, daD die Farbmolekiile in die Makromolekulkette eingebaut sind.Die Untersuchungen wurden in Gegenwart von 0,l Gew.-'x Farbstoff durchgefiihrt. Kolorimetrisch wurde festgestellt, daD 85-90'x des Farbstoffs in das Polymere eingebaut werden. Eine so geringe Farbstoffmenge genugt vollkommen zur Herstellung von intensiv gefarbten Polymeren, ohne daD dies zu einer bedeutenden Herabsetzung des Molekulargewichts fuhrt. SUMMARY:The polymerization of styrene in the presence of some coloured anthraquinone and azoderivatives of 1,3,5-triazine, containing a group able to copolymerize, was investigated. The dependence of the polymerization rate of styrene from the character of the dye and the kind of its polymerization active group was determined. In the UV and visible spectra of the obtained coloured polymers maxima of absorption were observed, which were characteristic for the dyes, but were missing in the spectra of uncoloured polystyrene. This shows that the dyes are incorporated into the macromolecular chains. The investigations are carried out in the presence of 0 , l x dye. Colourimetrically it was found that 85-90x of the dye is incorporated in the polymer. This small initial concentration of the dye is sufficient to obtain intensively coloured polymers without a significant decrease of the molecular weight.
