N, N ', N '' - tris {2,4-bis (1-hydrocarbyl-oxy-2,2,6,6-tetramethyl-piperidin-4-yl) alkylamino -s- tree triazin-6-yl-3,3'-ethylenedioxy iminodiacetic propylamine, the polymer compositions stabilized by these and isomers thereof and a cross-linked derivative

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.
