Medical articles made from polyurethane-based resins containing modified oligomers provide improved properties. At least one modified oligomer, preferably two alcohol moieties (C-OH), is incorporated into the main chain of the polyurethane resin formed by the diisocyanate, polyglycol, and diol chain extender as a side chain or both. ) And has a functional part. Examples of modified oligomers are diol-containing perfluoropolyethers incorporated into the backbone, monofunctional polysiloxanes incorporated as side chains (eg, monodialcohol-terminated polydimethylsiloxanes), and combinations thereof. The medical articles herein are self-lubricating and / or antifouling. |
