Abstract
Abstract Flame retardant compositions comprising admixtures of polyphenylene ether resin, a polyalkenyl aromatic and as the sole flame retardant agent, a halogenated aromatic compound or mixture of such compounds, are described. These provide decided advantages over corresponding flame retardant compositions containing synergistic agents and/or aromatic phosphate flame retardants, alone, or in combination with halogenated aromatics. They are useful for shaping into a wide variety of articles for industrial or household purposes.

Claims Analysis
Total Claims: 33
Claim 1
Independent Claim
49 words
A flame retardant thermoplastic composition, comprising a normally flammable blend of (a) a polyphenylene ether resin and (b) a poly(alkenyl aromatic); and (c) a minor, flame retardancy improving amount of a halogenated aromatic flame retardant compound or compounds in the absence of any synergist or other flame retardant agent.
Claim 2
Dependent Claim
49 words
A flame retardant thermoplastic composition, comprising a normally flammable blend of (a) a polyphenylene ether resin and (b) a poly(alkenyl aromatic); and (c) a minor, flame retardancy improving amount of a halogenated aromatic flame retardant compound or compounds in the absence of any synergist or other flame retardant agent.
Claim 3
Dependent Claim
61 words
A composition according to Claim 1, in which the polyphenylene ether resin is a homopolymer or copolymer comprising units of the formula wherein Q, Q', Q" and Q''' are independently selected from the group consisting of hydrogen, halogen, hydrocarbon, halohydrocarbon, hydrocarbonoxy, and halohydrocarbonoxy; and n represents the total number of monomer units and is an integer of at least about 20.
Claim 4
Dependent Claim
16 words
