New method for preparation of poly(enamino-enaryloxynitriles) and thermal properties

A kinetic study an enaryloxynitriles via nucleophilic vinylic substitution reactions of various phenol derivatives with 1-chloro-1-phenyl-2,2-dicyanoe thene was conducted in the presence of 1,4-diazabicyclo[2, 2,2] octane (DAB CO). The reaction was applied to solution polymerization of diphenol and di amine derivatives with p-bis(1-chloro-2,2-dicyanovinyl)benzene, which gave various poly(enamino-enaryloxnitriles) with moderate molecular weights in g ood yields. Thermal properties such as thermal curing and thermal stability were examined by differential scanning calorimetry and thermogravimetric a nalysis. The poly(enamino-enaryloxynitriles) showed similar curing to typic al polyenaminonitriles and polyenaryloxynitriles.
