The major nonvolatile products of oxidation for norbornenyl-end capped PMR polyimide resins proceeds through two primary pathways. Path A degradation is proposed to proceed through initial opening of the norbornenyl ring to form a biradical which undergoes attack of oxygen to form a 2-hydroxy substituted maleimide. Path B degradation proceeds through oxidation of the bridging methylene of the nonborne moieties followed by carbon monoxide extrusion.
