| 1. A soluble polymer prepared from at least one monomer of the formula:
A-R7—X—C(O)—C(R8)═CH2 wherein A is selected from the group consisting of functional groups having the following formulas:
 R1 and R2 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;
R3 is an alkyl, aryl, aralkyl, or —NRaRb wherein Ra and Rb 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;
R4 and R5 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;
R6 is an alkyl, fluoroalkyl, chloroalkyl, aryl, —NRcRd wherein Rc and Rd 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 R6 taken together with Re 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)Re wherein Re together with R6 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;
Y1, Y2, and Y3 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, —NRf— where Rf is hydrogen or alkyl, and combinations thereof;
X is —N(R9)— or —O—;
R7 is a divalent group selected from the group consisting of alkylene, heteroalkylene, arylene, heteroarylene, and combinations
thereof, wherein the alkylene and heteroalkylene optionally include one or more carbonyls;
R8 is hydrogen or methyl; and
R9 is hydrogen or a C1-6 alkyl group.
