Patent

CA 2228505

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) .infin.-.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.

L'invention concerne un mélange d'un polymère, de préférence un polyuréthanne, et d'une macromolécule compatible, à propriétés modificatrices de surface. Cette macromolécule a (i) une portion centrale constituée d'un copolymère bloc oligomère segmenté comprenant au moins un segment polaire dur et (ii) des groupes terminaux (en PROPORTIONAL et en omega ) oligomères polyfluorés, en dose suffisante pour modifier les propriétés de surface. La composition sert à réaliser des articles présentant des propriétés de surface améliorées et, en particulier, des dispositifs médicaux à résistance accrue à la dégradation enzymatique et une compatibilité acceptable avec le sang.
