Abstract
As new compositions of matter, 1,14-bis(3-amino-4-hydroxyphenyl)perfluoro-5,10-dimethyl-3,6,9,12-tetraoxa tetradecane and 1,17-bis(3-amino-4-hydroxyphenyl)perfluoro-3,6,9,15-tetraoxaheptadecane. The compounds are useful as monomers in synthesizing perfluoroalkylene ether bibenzoxazole polymers possessing thermooxidative stability and superior low temperature viscoelastic properties.
