ABS-moulding compositions with improved flame resistance

摘要

ABS-moulding compositions consisting of a thermoplastic copolymer and a graft polymer with rubber-like graft base exhibit an improved flame resistance if the total mixture contains a compound corresponding to the formulae <IMAGE> <IMAGE> polymerized into one or both components, wherein R1 represents C2-C6-alkylene, R2 represents hydrogen or methyl, R3 represents a direct bond or C1-C4-alkylene, and R4 represents hydrogen, methyl or CH2-OOC-CH2-CO-CH3.
