PURPOSE: To provide the titled compsn. having excellent light stability, heat resistance and non-extractibility, by blending a cyanurate derivative contg. a 2,2,6,6-tetramethylpiperidyl group with a high-molecular material. n CONSTITUTION: Cyanuric chloride is reacted with a compd. of formula I (wherein -ATU- is a group of formula II). The product is reacted with an amine of formula III [wherein R 1 , R 2 are each H, alkyl or R 1 , R 2 may form (oxadi)alkylene when combined together]. If desired, alkylation or acylation is carried out to obtain a cyanurate derivative (A) contg. a 2,2,6,6-tetramethylpiperidyl group and having formula IV (wherein R is H, alkyl, alkenyl, acyl, oxyl; n is 2W40). 0.001W5pts.wt. component A is blended with 100pts.wt. high-molecular material such as PE. n COPYRIGHT: (C)1987,JPO&Japio |
