Polymerizations by 1,3-Dipolar Cycloaddition Reactions. V. The 1,3-Dipolar Polycycloadditions of Dinitrile N -Oxides with Diolefins

Abstract

Terephthalonitrile di-N-oxide and isophthalonitrile di-N-oxide were synthesized from the corresponding hydroxamic chlorides by dehydrochlorination with triethylamine. Their chemical properties and the polycycloadditions with diolefins were examined. The polymers obtained were amorphous and their molecular weights were not so high. The thermal gravimetric analyses of them showed that the polymers were stable up to 300–350°C in air.
