Abstract

A compsn. (A) is claimed, contg.: (a) 25-99 wt. % organic phosphite or phosphonite; (b) 0.01-50 wt. % organic amine; and (c) 0.01-25 wt. % acid-binding metal salt. Also claimed is a method for stabilising organic phosphites and/or phosphonites (a) against hydrolysis, by adding (b) and (c) in the above amts. as stabilisers. Further claimed is a stabilised organic phosphite or phosphonite obtd. by this process.
