Blend compositions comprise a polyphenylene ether resin, a polyetherimide siloxane copolymer and pentaerythritol tetrabenzoate. The polyetherimide siloxane copolymer is preferably included in an amount sufficient to provide the compositions with improved flame retardant properties while the pentaerythritol tetrabenzoate is preferably included in an amount sufficient to lower the melt viscosity of the blend compositions. The compositions may further include an impact-modifying rubber compound, preferably a block copolymer of a vinyl aromatic hydrocarbon and an alkene or post-hydrogenated diene hydrocarbon.
