Abstract
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 2 , --NHCH 3 , --NH--NH 2 , --OCH 3 , --OC 2 H 5 , --CH 3 or --C 2 H 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.
