Abstract
The synthesis of new stabilizer compounds (a combination between 2,2,6,6-tetramethylpiperidine and 2-hydroxyphenylbenzotriazole in one molecule) is reported. Four polymerisable combined stabilizers as well as two unsaturated triazinyl-2,2,6,6-tetramethylpiperidines and two unsaturated triazinyl-2-hydroxyphenylbenzotriazoles as individual stabilizers were synthesized. Their copolymers and terpolymers of the individual stabilizers with acrylonitrile were obtained. Chemical bonding of the stabilizers in the polymer was confirmed spectrophotometrically. The influence of these additives on the photo-stability of the copolymers was studied. The participation of the combined stabilizers in the polymerisation did not significantly affect the molecular weight and polydispersity of the copolymers. A significant stabilizing effect against photodegradation was found.
