ABSTRACT:
Compositions comprising a polyphenylene ether and, optionally, a styrene resin, an aromatic phosphate, phosphonate or phosphine oxide, an aromatic halogen compound and an impact modifier comprising a diene polymer have excellent flame retardant properties during large scale flammability tests. The compositions will tolerate large amounts of aromatic halogen compound without discoloration and processing difficulties. In comparison with compositions of the present state of the art, peak burn temperatures are reduced, smoke is less dense, and flaming drips are eliminated in large as well as small scale burn tests.
