    Abstract: Disclosed herein are methods and thermoplastic compositions of blended polycarbonate thermoplastic compositions with improved thermal resistance and conductivity. The resulting blended polymer thermoplastic compositions, comprising at least one aromatic polycarbonate; at least one high heat 3,3-bis(4-hydroxyphenyl)-2-phenylisoindolin-1-one (PPPBP)-polycarbonate copolymer; at least one polycarbonate-siloxane copolymer; and at least one laser direct structuring additive; wherein the laser direct structuring additive is a filler selected from a metal oxide; a metal oxide coated filler; or a combination thereof; wherein the composition is capable of being plated after being activated using a laser; and wherein the composition has a heat distortion temperature higher than 150 degrees Celsius, as determined by ASTM D 648.
