Synthesis of Novel Bifunctional Hindered Amine-UV Absorber Polymer Stabilizers

摘要

Stabiliser compounds were synthesised from a combination of 2,2,6,6-tetramethylpiperidine and 2-hydroxyphenylbe nzotriazole in one molecule.Four polymerisable combined stabilisers,as well as two unsaturated triazinyl-2,2,6,6-tetramethylpiperidines and two unsaturated triazinyl-2-hydroxyphenylbenzotriazoles as individual stabilisers,were synthesised.
