Patent ID: 7342082

Claim:
A soluble polymer having two or more pendant groups independently selected from the group consisting of functional groups having the following formulas: wherein; R 1 and R 2 together with a dicarboximide group to which they are attached form a four to eight membered heterocyclic or heterobicyclic group that can be fused to an optional aromatic group, optional saturated or unsaturated cyclic group, or optional saturated or unsaturated bicyclic group; R 3 is an alkyl, aryl, aralkyl, or —NR a R b wherein R a and R b are each an alkyl group or taken together with the nitrogen atom to which they are attached form a four to eight membered heterocyclic group; R 4 and R 5 together with a dicarboximide group to which they are attached form a four to eight membered heterocyclic or heterobicyclic group that can be fused to an optional aromatic group, optional saturated or unsaturated cyclic group, or optional saturated or unsaturated bicyclic group; R 6 is an alkyl, fluoroalkyl, chloroalkyl, aryl, —NR c R d wherein R c and R d are each an alkyl group or taken together with the nitrogen atom to which they are attached form a four to eight membered cyclic group, or R 6 taken together with R e and the groups to which they are attached form the four to eight membered heterocyclic or heterobicyclic group that can be fused to the optional aromatic group, optional saturated or unsaturated cyclic group, or optional saturated or unsaturated bicyclic group; Z is an alkyl, aryl, or —(CO)R e wherein R e together with R 6 and groups to which they are attached form a four to eight membered heterocyclic or heterobicyclic group having a nitrogen heteroatom and a sulfur heteroatom, wherein said heterocyclic or heterobicyclic group can be fused to an optional aromatic group, optional saturated or unsaturated cyclic group, or optional saturated or unsaturated bicyclic group; Y 1 , Y 2 , and Y 3 are each independently a single bond or a divalent group selected from the group consisting of an alkylene, heteroalkylene, arylene, carbonyl, carbonyloxy, carbonylimino, oxy, thio, —NR f — where R f hydrogen or alkyl, and combinations thereof; and Y 4 and Y 5 are each a bond.
