摘要：

The thermal behavior of a series of polybenzoxazines based on 3-aminophenylacetylene has been investigated. The effect of reactive amine on the thermal cleavage of the Mannich base is examined under both inert and oxidative environments. It has been shown that the thermal stability of polybenzoxazines is substantially improved by the reactive amine. Various biphenols are found to have insignificant effect on the thermal stability of this series of polybenzoxazines. These nitrogen containing phenolic resins are nonflammable polymers.
