Stabilized synthetic polymer composition

Abstract

Abstract PURPOSE:To provide the title compsn. having excellent resistances to degeneration by oxidation and to accelerated degeneration by a heavy metal, by blending a synthetic polymer with a specific benzotriazole compd. CONSTITUTION:A reaction product of benzotriazolecarboxylic acid (reactive derivative thereof) with hydrazine is reacted with an ester or acid chloride of an org. monocarboxylic acid of formula I (wherein R1 is an org. monocarboxylic acid residue), an aldehyde or ketone of formula II (wherein R2-3 are each H, or alkyl, aryl or a substd. group thereof), or an ester or acid chloride of an org. dicarboxylic acid of formula III (wherein R4 is an org. dicarboxylic acid residue) to prepare a benzotriazole compd. (B) of formula IV-VI. Subsequently, 100pts.wt. synthetic polymer (A) (e.g., PE) is blended with 0.001-5pts.wt. component B.
