A polymer of the formula:
- where R1-R12 are independently chosen from a hydrogen, a C1-C10 monovalent hydrocarbon group optionally containing a hetero atom, a C6-C20 monovalent aromatic group optionally containing a hetero atom, and a C4 to C30 monovalent saturated or unsaturated cycloalkyl group optionally containing a hetero atom, siloxy group containing 1-20 silicone atoms, Z1 or Z2;
- Z1 and Z2 are independently chosen from a hydrogen, C1-C10 hydrocarbon group optionally containing heteroatom, —OH, —NH2, —COOH, or R16-A-R17— where A is chosen from a group comprising a unsaturated cyclic group chosen from an aromatic group, a functionalized aromatic group, a fused aromatic group optionally containing a heteroatom, a unsaturated alicyclic group, a unsaturated heterocyclic group, or a combination of two or more thereof;
- R16 and R17 are independently chosen from a nil, C1-C10 hydrocarbon group optionally containing a hetero atom, a C6-C20 aromatic group optionally containing a hetero atom, and a C4 to C30 saturated or unsaturated cycloalkyl group optionally containing a hetero atom;
- Z3 is chosen from —R19-A-R19— where A is chosen from a group comprising a unsaturated cyclic moiety chosen from an aromatic group, a fused aromatic group, an unsaturated alicyclic group, an unsaturated heterocyclic group, or a combination of two or more thereof;
- and R19 is chosen from a nil, C1-C10 hydrocarbon group optionally containing a hetero atom, a C6-C20 aromatic group optionally containing a hetero atom, and a C4 to C30 saturated or unsaturated cycloalkyl group optionally containing a hetero atom;
- m is 1-100;
- x is 0-200;
- and y is 0-200, wherein x+y≥1.
