Abstract:

The research described in this report is directed toward the development of a universal crosslinking agent for aromatic and aromatic heterocyclic polymers. The syntheses of materials capable of forming reactive intemediates at elevated temperature are discussed. Initial experiments on the crosslinking capabilities of several crosslinking agents are discussed. Investigation into the use of peroxides as crosslinking additives involves the synthesis of high molecular weight peroxides. Four peroxides of varying molecular weights and aromatic character have been synthesized. The effectiveness of these additives has been tested on a variety of aromatic polymers. The crosslinking effectiveness of a high molecular weight carbene precursor, 4,4-Bisalpha-diazobenzyldiphenyl ether, has been tested with both model compounds and aromatic polymers.
