Document Type and Number:
Japanese Patent JP7411644
Kind Code:
B2
Abstract:
Medical articles formed from a polyurethane-based resin including a modifying oligomer provide enhanced properties. A modifying oligomer incorporated into a backbone, as a side chain, or both of the polyurethane-based resin formed by a diisocyanate, a polyglycol, and a diol chain extender has at least one, preferably two, alcohol moieties (C—OH) and a functional moiety. Exemplary modifying oligomers are: a diol-containing perfluoropolyether incorporated into the backbone, a monofunctional polysiloxane (e.g., monodialcohol-terminated polydimethylsiloxane) incorporated as the side chain, and combinations thereof. Medical articles herein are self-lubricating and/or anti-fouling.
