B. von 1:0,1 bis 1:5 betragen.
- Die Erfindung betrifft weiterhin ein Verfahren zur Stabilisierung eines Polyolefins gegenüber lichtbedingtem Abbau, das den Zusatz der Komponenten A), B) und C) wie in Anspruch 1 definiert umfasst, mit der Maßgabe, dass in dem Polyolefin die Anwesenheit eines weiteren sterisch gehinderten Amins außer der Komponente A) ausgenommen ist.
- Das nachstehende Beispiel veranschaulicht die Erfindung eingehender. Sämtliche Prozentangaben und Teile, sind, wenn nicht anders angegeben, auf Gewicht bezogen.
- Beispiel 1
- Lichtstabilisierung in Polypropylen-Homopolymerisatfilmen 100 Teile eines nichtstabilisierten Polypropylenpulvers (Schmelzindex: ~2,4 g/10 Minuten, gemessen bei 230°C/2160 g) werden 10 Minuten bei 200°C in einem Brabender-Plastographen mit 0,05 Teilen Pentaerythrit-tetrakis-3-(3,5-di-tert.-butyl-4-hydroxyphenyl)-propionat, 0,05 Teilen Tris-(2,4-di-tert.-butylphenyl)-phosphit und der in Tabelle 1 angegebenen Stabilisatormischung homogenisiert. Das so erhaltene Material wird in einer Laboratoriumspresse zwischen zwei Aluminiumfolien 6 Minuten bei 260°C zu einem 0,5 mm dicken Film preßgeformt, welcher unmittelbar auf Raumtemperatur in einer wassergkühlten Presse abgekühlt wird. Proben von 60 mm × 25 mm werden aus diesen 0,5 mm–Filmen herausgeschnitten und in einem WEATER-OMETER Ci65 (Schwarztafeltemperatur 63 ± 2°C ohne Wassersprühen) belichtet.
- Diese Proben werden periodisch aus der Belichtungsapparatur entfernt, und ihr Carbonylgehalt wird mit einem Infrarot-Spektralphotometer bestimmt.
- Die Belichtungszeit, die der Bildung einer Carbonylextinktion von 0,1 entspricht, ist ein Maß für die Wirksamkeit der Stabilisatormischung. Die erhaltenen Werte werden in Tabelle 1 wiedergegeben. Tabelle 1
Stabilisatormischung Zeit bis zu einer Carbonylextinktion von 0,1 in Stunden 0,05% von (A), 0,1% Zinkstearat und 0,5% TiO2 (Rutil) 1470 Vergleich: Stabilisatormischung gemäß US-A-4 929 652 0,05% von (XX), 0,1% Zinkstearatund 0,5% TiO2 (Rutil)1230 - Der Mittelwert von n beträgt 5,1.
