Claim 0:
1. A polyimide polymer, comprising the reaction product of components (a), (b), (c), and (d), wherein components (a), (b), (c), and (d) are:
(a) at least one diamine selected from the group consisting of a diamine of Structure (Ia) and a diamine of Structure (Ib):, , wherein each of R1, R2, R3, R4, R5, R11, R12, R13, and R14 ndependently, is H, a substituted or unsubstituted C1-C6 linear or branched alkyl group, or a substituted or unsubstituted C5-C7 cycloalkyl group,
(b) at least one diamine selected from the group consisting of a diamine of Structure (IIb) and a diamine of Structure (IIc):, , wherein each R20, independently, is a hydrogen atom, a substituted or unsubstituted C1-C6 linear or branched alkyl group, or a substituted or unsubstituted phenyl group, each R22, independently, is a substituted or unsubstituted C1-C6 linear or branched alkylene group, R23 is a substituted or unsubstituted C1-C20 linear or branched alkyl group or a C6-C20 substituted or unsubstituted aryl group, and R24 is a S atom, —NR25—, —CH(R25)—, or —(CH2)2—, in which R25 is a C1-C6 substituted or unsubstituted linear or branched alkyl group,
(c) at least one tetracarboxylic acid dianhydride, and
(d) at least one compound comprising a first functional group reactive with an amine or an anhydride and at least a second functional group selected from the group consisting of a substituted or unsubstituted alkenyl group and a substituted or unsubstituted alkynyl group.
