Abstract
Abstract A thermoplastic moulding composition which comprises: (A) from 99.99 to 94% by weight of an ABS composition comprising: (a) from 5 to 70% by weight of one or more rubber-based graft polymers; and (b) from 95 to 30% by weight of one or more thermoplastic resins; and (B) from 0.01 to 6.0% by weight of one or more compounds corresponding to the following general formula: ##STR1## wherein R represents hydrogen, C 1 -C 4 -alkyl or carboxyl; R 1 represents hydrogen or methyl; and R 2 represents carboxyl, and which may also contain from 0.1 to 3% by weight of one or more compounds corresponding to the formula: ##STR2##
