Abstract
A kinetic study on enaryloxynitriles via nucleophilic vinylic substitution reactions of various phenol derivatives with 1-chloro-1-phenyl-2,2-dicyanoethene was conducted in the presence of 1,4-diazabicyclo[2,2,2]octane (DABCO). The reaction was applied to solution polymerization of diphenol and diamine derivatives with p-bis(1-chloro-2,2-dicyanovinyl)benzene, which gave various poly(enamino-enaryloxynitriles) with moderate molecular weights in good yields. Thermal properties such as thermal curing and thermal stability were examined by differential scanning calorimetry and thermogravimetric analysis. The poly(enamino-enaryloxynitriles) showed similar curing to typical polyenaminonitriles and polyenaryloxynitriles.
