Resumo

Two new unsaturated compounds, i. e. triazinyl-2,2,6,6-tetramethylpiperidine derivatives (TTMP), were synthesized under conditions of phase-transfer catalysis and their copolymers with styrene (St) were prepared. The participation of TTMP in the polymerization did not affect the rate of copolymerization, molecular weight and polydispersity of the St polymers. At low concentrations (0.1 wt.-%) a significant stabilizing effect against photodegradation was determined. Zwei neue ungesättigte Derivate auf der Basis von Triazinyl-2,2,6,6-tetramethylpiperidin (TTMP) wurden unter Phasentransferkatalyse-Bedingungen synthetisiert und mit Styrol (St) copolymerisiert. TTMP beeinflußt kaum die Geschwindigkeit der Copolymerisation, das Molekulargewicht und die Molekulargewichtsverteilung der Styrol-Polymeren. Bei niedrigen Konzentrationen (0,1 Gew.-%) wurde eine deutliche Stabilisierung gegen Photoabbau festgestellt.
