Abstract:

Benzoxazine with allyl group and alkyne group prepared by using 3ethynylaniline, diallylbisphenol A and formaldehyde in 1,4dioxane was synthesized, and characterized by 1H NMR and FTIR in this paper. The benzoxazine compound is liquid in room temperature. Dynamic mechanical analysis (DMA) was used for analyzing the cured product of benzoxazine compound. The results show that the cured product of benzoxazine compound has higher application temperature, its glass transition temperature can reach 367.61℃. Therefore,it could be used as a resin matrix of high performance composite.

Key words: benzoxazine, synthesis, characterization
