摘要
以1-萘酚、对苯二甲醇、烯丙基氯等合成出新型缩合多核芳烃(COPNA)树脂。采用FT-IR和1H-NMR研究了COPNA树脂的化学结构;通过凝胶分析研究了COPNA与双马来亚酰胺的共聚反应性;采用TG-DTG研究了这种共聚树脂的热稳定性。研究表明,COPNA树脂结构中含有烯丙基活性基团,可与BMI发生共聚反应制备耐热性优良的树脂体系。
In order to obtain a high-performance resin matrix for advanced polymeric composites （APC）, a new condensed polynuclear aromatic （COPNA） resin containing allyl was synthesized using 1-hydroxy naphthalene, 1, 4-benzenedimethanol, allyl-chlorine, and so on. The chemical structures of the COPNA resin were characterized by FT-IR and ^1H-NMR, and the copolymerization reactivity of the COPNA resin and bismaleimide （BMI） was studied through gel analysis. Moreover, TG-DTG was employed to study the thermal behavior of the copolymer of the COPNA resin and BMI. The results show that the COPNA resin has high reactivity with BMI due to the active group of allyl, and the resulting copolymer possesses excellent thermo-stability and high coke value.
