Abstract
A composition includes a polycarbonate-polysiloxane block copolymer that has at least one polycarbonate block and at least one polysiloxane block, and a surface modifying agent that includes at least one polysiloxane segment. Increased levels of the surface modifying agent can be incorporated without compromising high transmittance and low haze. The compositions also exhibit improved hemocompatibility and are therefore useful for a variety of articles that may contact blood.
