Abstract

Chlorine-containing thermoplastics containing, as the stabilizer, at least one compound of the formula I ##STR1## wherein m is the number 0, 1 or 2, n is the number 1, 2 or 3, P is the number 1 or 2, Hal is --F, --Cl, --Br or --I, X is --NH.sub.2, --NHCH.sub.3, --NH--NH.sub.2, --OCH.sub.3, --OC.sub.2 H.sub.5, --CH.sub.3 or --C.sub.2 H.sub.5, Y is --CO-- and R is as defined in claim 1, are described. A process for the preparation of (substituted) anthranilic acid amides is also described.
