Abstract : Omega-carbomethoxyperfluoroalkylene ether iodides are reacted with metallic zinc to yield alpha-omega perfluoroalkyleneether diesters. The diesters are reacted with ammonia to form diamides, the diamides are reacted with phosphorus pentoxide to form dinitriles, and the dinitriles are esterfied with methanol to form diimidate esters. The diimidate esters are particularly useful as monomers in synthesizing perfluoroalkylene ether bibenzoxazole polymers possessing thermooxidative stability and outstanding low temperature viscoelastic properties.
