The derivatives of 2-(2-hydroxyphenyl)-2Hbenzotriazole (HBT) and 2,2,6,6-tetramethylpiperidine (HALS) are among the most effective stabilizers used, so their polymerizable derivatives have been the objects of many investigations. The combination of different types and chemical structures of stabilizers, acting according to different mechanisms, is a very promising method to obtain a new type of stabilizer. The influence of these compounds on the photostability of copolymers with some vinyl monomers was demonstrated. New approaches for ``one-step`` coloration and stabilization of polymers by a combination ``in-one molecule`` of a chromophore and a stabilizer were described. Two of the possibilities are presented - when the stabilizer and the chromophore are combined in-one molecule through an s-triazine ring and - when the stabilizer's fragment is connected directly to the chromophore.enArticle
