Claims7
An indane bis-o-aminophenol compound having formula Ia:
- wherein each of R1, R2, R3, R4, and R5 independently, is a hydrogen atom, a substituted or unsubstituted C1-C12 alkyl, a partially halogen substituted or fully halogen substituted C1-C12 alkyl, a substituted or unsubstituted C4-C18 cycloalkyl, a substituted or unsubstituted C6-C22 aryl, or a substituted or unsubstituted C5-C22 heteroaryl;
- each of R11 and R12 is independently a hydrogen atom, a linear or branched C1-C4 alkyl, a partially halogen substituted or fully halogen substituted C1-C4alkyl, a C4-C12 cycloalkyl, a C6-C18 aryl, a C5-C18 heteroaryl group, a C1-C4 alkoxy group or a halogen atom.
A polymer comprising a poly-o-hydroxyamide represented by the following general formula (II):
- wherein each of R1, R2, R3, R4, and R5 independently, is a hydrogen atom, a substituted or unsubstituted C1-C12 alkyl, a partially halogen substituted or fully halogen substituted C1-C12 alkyl, a substituted or unsubstituted C4-C18 cycloalkyl, a substituted or unsubstituted C6-C22 aryl, or a substituted or unsubstituted C5-C22 heteroaryl;
- each of R11 and R12 independently is a hydrogen atom, a linear or branched C1-C4 alkyl, a partially halogen substituted or fully halogen substituted C1-C4 alkyl, a C4-C12 cycloalkyl, a C6-C18 aryl, C5-C18 heteroaryl group, a C1-C4 alkoxy group or a halogen atom;
- Ar1 and Ar2 are a divalent aromatic, aliphatic, or heterocyclic group, or mixtures thereof;
- Ar11 is a divalent aromatic, aliphatic, or heterocyclic group or siloxane group;
- E is an end-capping group;
- m1 is an integer from 5 to 200;
- n1 is an integer from 5 to 200;
- m2 is an integer from 0 to 200 and n2 is an integer from 0 to 200.
