Claim:
1. An electrostatic dissipative thermoplastic composition comprising: (i) an aromatic polycarbonate polymer; (ii) a thermoplastic polyurethane-based inherently dissipative polymer comprising the reaction product of at least one polyol intermediate, at least one diisocyanate, and at least one chain extender; and (iii) a compatibilizer comprising a thermoplastic polyurethane wherein said compatibilizer thermoplastic polyurethane comprises the reaction product of at least one polycaprolactone polyol, at least one diisocyanate, wherein the diisocyanate is selected from 4,4′-methylene diphenyl diisocyanate, dicyclohexylmetheno-4,4′-diisocyanate, or combinations thereof, and at least one alkylene diol chain extender; wherein the polyol intermediate used to prepare component (ii) is different from that used to prepare component (iii).
