Patent ID: 8592493

Claim:
A method for preparing an article, the method comprising providing an azlactone-functionalized support of Formula (I) wherein SS comprises a solid support; p is an integer equal to 0 or 1; and each R 1 is independently selected from alkyl, heteroalkyl, aryl, or aralkyl; forming a (meth)acryloyl-functionalized support of Formula (II) SS—(CO)—NH—C(R 1 ) 2 —(CH 2 ) p —(CO)-Q-Y 1 -Q-(CO)—CR 2 ═CH 2 (II) from the azlactone-functionalized support of Formula (I) wherein each group Q is independently a divalent group selected from oxy, thio, or —NR 3 — where R 3 is a hydrogen, alkyl, heteroalkyl, aryl, or aralkyl; Y 1 is a first linking group comprising an alkylene, heteroalkylene, arylene, or combination thereof; and R 2 is hydrogen or an alkyl; polymerizing the (meth)acryloyl-functional support of Formula (II) with a monomer composition that comprises a monomer of Formula (III) Z 1 —Y 2 —CR 2 ═CH 2 (III) to form a grafted support of Formula (IV) SS—(CO)—NH—C(R 1 ) 2 —(CH 2 ) p —(CO)-Q-Y 1 -Q-(CO)—CR 2 U 2 —CH 2 —U 1 (IV) wherein U 1 comprises at least one divalent monomeric unit of formula —CR 2 (Y 2 Z 1 )—CH 2 —; U 2 is hydrogen or comprises at least one divalent monomeric unit of formula —CR 2 (Y 2 Z 1 )—CH 2 —; Z 1 is a functional group selected from (1) an acidic group or a salt thereof, (2) an amino group or a salt thereof, (3) a hydroxyl group, (4) an azlactone group or a precursor of the azlactone group, (5) a glycidyl group, or (6) a combination thereof; and Y 2 is a second linking group selected from a single bond or a divalent group comprising an alkylene, heteroalkylene, arylene, or combination thereof.
