Patent ID: 8637610

Claim:
A crosslinked polymer comprising: (A) a linear, branched or cyclic polymeric backbone comprising repeat units that comprise one or more groups selected from: hydrocarbylene groups, heteroatoms, and carbonyl groups; wherein the hydrocarbylene groups are aliphatic or aromatic, linear, branched, or cyclic, and combinations thereof; and (B) one or more crosslinking units containing at least one aldaroyl structural unit of Formula I: wherein: (i) the hydrocarbylene groups and heteroatoms of the repeat units are substituted with substituents that comprise one or more of C 1 -C 30 hydrocarbylene groups, heteroatoms, and carbonyl carbon groups, and wherein the hydrocarbylene groups of the substituents are aliphatic or aromatic, linear, branched, or cyclic, or combinations thereof; and (ii) the substituents on the hydrocarbylene groups and heteroatoms of the repeat units comprise one or more of: —X; —OZ; —NZZ′; —N + ZZ′Z″; —COOZ; —COX; —CONZZ′; —CNO; —O—; —NZ—; —N + ZZ′—; —CONZ—; —COO—; —CO—; —OCOO—; —OCONZ—; —N(Z)CONZ′—, —CONH(CH 2 ) p NH 2 , —Si(ZZ′)O—, —(OCH 2 CH 2 ) m OH, or —(OSi(ZZ′)) n OH, and salts thereof, wherein X is a halogen, Z, Z′, and Z″ are independently hydrogen or C 1 -C 22 alkyl, substituted alkyl, aryl, or substituted aryl, and wherein m is 1 to 50, n is 1 to 100, and p is 1 to 12.
