Synthesis and properties of some new blue-emitting triazine derivatives of 2-aminoterephthalic acid, containing a polymerisable group and stabiliser fragment / Polya M. Miladinova in COLORATION TECHNOLOGY, Vol. 125, N° 4 (2009)  

[article]  inCOLORATION TECHNOLOGY > Vol. 125, N° 4 (2009) . - p. 242-247 Titre : Synthesis and properties of some new blue-emitting triazine derivatives of 2-aminoterephthalic acid, containing a polymerisable group and stabiliser fragment Type de document : texte imprimé Auteurs : Polya M. Miladinova, Auteur ; Temenushka N. Konstantinova, Auteur Année de publication : 2009 Article en page(s) : p. 242-247 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 667.3 Teinture et impression des tissus Résumé : Seven new blue-emitting triazine derivatives of 2-aminoterephthalic acid were synthesised, two of which contained a polymerisable group, one a stabiliser fragment and two containing both a polymerisable group and a stabliser fragment. The synthesised compounds were characterised by analytical methods. The ability of four of the derivatives to copolymerise with methylmethacrylate was demonstrated, thus they can be used for obtaining polymers with a whiteness and fluorescence stable to solvents. Two of the compounds, containing a combination of a stabiliser fragment and a polymerisable group, can be used for 'one-step' stabilisation and whitening of polymer materials. All the compounds, possessing an intense blueish fluorescence, are suitable as fluorescent whitening agents for textiles.

Synthesis of some symmetrically substituted stilbene-triazine derivatives containing tetramethylenepiperidine fragments and their application to make self-whitening polyacrylonitrile / Polya M. Miladinova in COLORATION TECHNOLOGY, Vol. 131, N° 4 (08/2015)

Langues : Anglais (eng) Catégories : Agents de blanchiment Composés organiques -- Synthèse Copolymérisation Fluorescence Photostabilité Polyacrylonitrile Index. décimale : 667.3 Teinture et impression des tissus Résumé : This study reports the synthesis of nine new fluorescent stilbene-triazine whitening agents containing a tetramethylpiperidine fragment. These products were isolated and characterised by spectroscopic techniques, i.e. infrared, ultraviolet, and fluorescent spectra, and confirmed by proton nuclear magnetic resonance spectroscopy. The photostability of the new compounds and two optical brighteners containing an unsaturated group without a stabiliser fragment was studied. It was found that the compounds containing tetramethylpiperidine have better photostability. The possibility of the copolymerisation of the unsaturated compounds with acrylonitrile was investigated, and self-whitening polymers with an intense blue fluorescence were obtained. It was established that 85–86% of the fluorophores are chemically bound to the polymer chain.
