Disclosed herein are blended thermoplastic compositions comprising at least one polycarbonate component, at least one polybutylene component, at least one polyester ether elastomer component, at least one poly(ethylene-co-ethylacrylate) component, at least one ethylene/alkyl acrylate/glycidyl methacrylate terpolymer component, and at least one glass fiber component. The thermal blended polycarbonate compositions can optionally further comprise a transesterification quenching agent and/or epoxy hydrostabilizer agent. The resulting compositions can be used in the manufacture of articles requiring materials that have high impact strength yet have very high stiffness, while retaining desired dielectric properties and are colorable from white to black.
