Abstract
The invention relates to impact-modified polymer compositions, containing a polymer blend of polycarbonate with polyester and/or polyamide, plus an impact modifier blend of core/shell and functional polyolefin impact modifiers. The impact modifiers can provide the polymer blend composition with improved impact strength at equivalent loading, and also allow for higher amounts of polyester and/or polyamide in the blend without sacrificing impact strength.
