Patent ID: 8519058

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 the hydrocarbylene groups and heteroatoms of the repeat units are optionally substituted with substituents that comprise one or more of C 1 -C 30 hydrocarbylene groups, heteroatoms, and carbonyl carbon groups, wherein the hydrocarbylene groups of the substituents are aliphatic or aromatic, linear, branched, or cyclic, or combinations thereof.
