A lubricious coating for a medical device is formed including first and second coated layers. The first coated layer is between the second coated layer and the device surface and includes a vinyl pyrrolidone polymer and a photo reactive group. The second coated layer is in direct contact with the first coated layer and is a top coating that includes an acrylic acid polymer. The second coated layer can optionally include photoreactive groups. The coating was found to have a very low number of particulates (e.g., 10 m or greater) which is very desirable for in vivo use.

The present invention provides a fluorine-containing ether compound represented by the following formula.
R.sup.1CH.sub.2R.sup.2CH.sub.2R.sup.3CH.sub.2R.sup.4CH.sub.2R.sup.5CH.sub.2R.sup.6CH.sub.2R.sup.7
(In Formula (1), R.sup.2, R.sup.4, and R.sup.6 are perfluoropolyether chains, R.sup.3 is Formula (2), R.sup.5 is Formula (3), and R.sup.1 and R.sup.7 are each independently a terminal group having two or three polar groups, in which individual polar groups are bound to different carbon atoms and the carbon atoms to which the polar groups are bound are bound to each other via a linking group containing a carbon atom to which no polar group is bound). ##STR00001##

A composition for reducing friction or stiction of a surface is disclosed. The composition comprises at least one organosilane, at least one organophosphorus, or a combination of at least one organosilane and at least one organophosphorus. The composition further comprises at least one polymer. Methods of applying the composition to a surface are also disclosed. Non-limiting examples of surfaces to which the composition can be applied include metal, metal alloys, metal oxide, glass, ceramic, or plastic substrates, and combinations thereof. Articles comprising at least one surface having been treated with the composition are also disclosed. Non-limiting examples of such articles include windows, watches and watch bands, screens, monitors, high-touch surfaces, electronic products, housing for electronics, and combinations thereof. Such articles can also exhibit enhanced hydrophobicity and/or anti-corrosion properties compared to untreated articles.
