N,N',N''-tris{2,4-bis[Hydrocarbyloxy-2,2,6,6-tetra-methylpiperidin-4-yl)alkylamino]-s-triazin-6-yl}-3,3'-ethylenediiminodipropylamines, their isomers and bridged derivatives and polymer compositions stabilized therewith

摘要

A mixture of the compounds identified in the title, their pure isomers and alkane-bridged derivatives are particularly effective in stabilizing polymer compositions, particularly polyolefin compositions.
