PURPOSE: To improve resistance to heat and weather, by blending a specified arom. amine compd. and a hindered amine light stabilizer with a polyether ester amide.

CONSTITUTION: 0.05W5pts.wt. arom. amine compd. (A) of formula I , II, III or IV(wherein R1, R1' are each H, a 1W18C hydrocarbon group, etc.; R2 is a 1W 12C alkyl) such as phenyl-α-naphthylamine and 0.05W5pts.wt. hindered amine light stabilizer (B) of formula V (wherein R3 is H, a 1W12C alkyl; R4, R4' are each a 1W6C alkyl; X is -O-, -NH-; R5 is a 1W23C hydrocarbon group, etc.; lis 1W4) such as 4-benzoyloxy-2,2,6,6-tetramethylpiperidine are blended with 100pts.wt. polyether ester amide (C) to obtain the desired polyether ester amide compsn.
