Abstract
Coatings are formed by applying to article a copolymer of a water soluble base polymer having graft polymerized thereto an organic moiety that includes a group that reacts with water to form a silanol group, and then curing the copolymer to form a crosslinked hydrogel coating that is absorbent, lubricious and substantially non-water soluble. Coating compositions, coated articles the subject coatings are also described.
Claims33
A method of forming a coating on an article, the method comprising contacting the article with a copolymer comprising a water soluble base polymer having graft polymerized thereto in a non-terminal position an organic moiety that includes a group that reacts with water to form a silanol group;
- and
- curing the copolymer to form a coating comprising the crosslinked copolymer on the article.
A coating on an article, the coating comprising a crosslinked hydrogel that includes a copolymer comprising water soluble base polymers having graft polymerized thereto organic moieties that react with water to form a silanol group, the copolymer being crosslinked through the silanol groups of the organic moieties to form a coating that is absorbent, lubricious and substantially non-water soluble.
A coated article comprising an article coated with a crosslinked hydrogel that includes a copolymer comprising water soluble base polymers having graft polymerized thereto organic moieties that react with water to form a silanol group, the copolymer being crosslinked through the silanol groups of the organic moieties to form a coating that is absorbent, lubricious and substantially non-water soluble.
A coating solution comprising a mixture of a solvent and a copolymer comprising a water soluble base polymer having graft polymerized thereto in a non-terminal position an organic moiety that includes a group that reacts with water to form a silanol group.
