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 ##STR1## polymerized into one or both components, wherein R.sub.1 represents C.sub.2 -C.sub.6 -alkylene,R.sub.2 represents hydrogen or methyl,R.sub.3 represents a direct bond or C.sub.1 -C.sub.4 -alkylene, andR.sub.4 represents hydrogen, methyl or CH.sub.2 --OOC--CH.sub.2 --CO--CH.sub.3.
