ABSTRACT:
A composition comprising in admixture with a polymer, preferably a polyurethane, and a compatible surface-modifying macromolecule having (i) a central portion of a segmented block oligomeric copolymer comprising at least one polar hard segment, and (ii) .varies.-.omega. terminal polyfluoro oligomeric groups, in a surface modifying enhancing amount. The composition is of use in providing articles having improved surface properties, particularly, medical devices having improved resistance to enzyme degradation with acceptable blood compatibility.
