Self-lubricating medical articles

摘要

Medical articles formed from polyurethane-based resins comprising modified oligomers provide improved properties. The modified oligomer incorporated into, as a side chain, or both into the backbone of the polyurethane-based resin formed by diisocyanate, polyglycol, and diol chain extenders comprises at least one, preferably two, alcohol moieties (C-OH) and It has a functional moiety. Exemplary modifying oligomers are diol-containing perfluoropolyethers incorporated into the backbone, monofunctional polysiloxanes incorporated as side chains (eg, monodialcohol-terminated polydimethylsiloxanes), and combinations thereof. Medical articles herein are self-lubricating and/or antifouling.
