The thermal properties of a PMR (polymerization of monomer reactants) polyimide resin chain terminated with various reactive monomers has been studied. Vinyl groups appear as efficient as ethynyl in providing crosslinks that are more thermally stable than those resulting from nadic ester endcapping. Terminal nitrile groups were found to be unreactive. Evidence for the curing mechanism of these resins is presented from infrared, thermogravimetric, and liquid chromatographic analyses.
