Provided is a thermoplastic blend comprising: A) 50 to 90% by weight, of at least one polymer selected from the group consisting of aromatic polycarbonate, aromatic polyestercarbonate and aromatic polyester; B) a rubber-modified vinyl (co) polymer and C) 2 wt. % to 30 wt. %, of an aromatic polyester-based thermoplastic polyurethane (TPU) having a difference between Vicat softening temperature and Tg of 135° C. to 210° C., wherein the Vicat softening temperature is at least 120° C.; and optionally D) 0 wt. % to 2 wt. %, of one or more additives selected from the group consisting of flame retardants, antistatic agents, thermal stabilizers, lubricants, demolding agents, colorants, and compatibilizers, wherein wt. %, all instances, is based on weight of the thermoplastic blend. The inventive blends have improved hydrolytic stability compared to PC/TPU blends.
