Abstract
A polyimide prepolymer blend including a first prepolymer component comprising a first polyimide oligomer having the formula E-[R]-Eand a second prepolymer component selected from M, a second polyimide oligomer having the formula E-[R]-E, and combinations thereof; where Rand Rindependently comprise: where n is from about 1 to about 5, V is a tetravalent substituted or unsubstituted aromatic monocyclic or polycyclic linking structure, R is a substituted or unsubstituted divalent organic radical. Eand Eindependently comprise crosslinkable functional groups. Mcomprises a mixture of monomeric compounds including a diamine component, a dianhydride component, and an end group component. The prepolymer blend, prior to cure, provides at least one predetermined prepolymer blend property; and when cured under suitable cure conditions, the prepolymer blend provides a crosslinked polyimide matrix having at least one predetermined crosslinked matrix property.
