Abstract

PURPOSE: To impart a polyolefin with superior stability against photodeterioration to the one obtained by conventional amine stabilizers, by compounding a polyolefin with a specific high molecular triazine derivative together with a pentaerythritol derivative.
CONSTITUTION: A compound of formula I (R is methyl) and distearyl pentaerythritordiphosphite of formula II are added as stabilizing agents to a polyolefin by kneading. The total amount of the stabilizing agents is 0.1W3.0wt%, pref. 0.2W 2.0wt% of the polyolefin. The combined use of the stabilizing agents affords synergistic effect. The compound of formula I is prepared by reacting 2,2,6,6-tetramethyl-4-n-octylamino-piperidine with a reaction product of cyanuric chloride and 1,6- bis(2,2,6,6-tetramethyl-4-piperidyl-amino)hexane.
