摘　　要：以对苯二甲醇为交联剂、1-萘酚为单体合成COPNA树脂,经烯丙基化处理后与BMI反应制备烯丙基COPNA-BMI共聚树脂。采用FT-IR研究预聚树脂的化学结构;采用黏度计分析预聚树脂的流变性能;采用DSC研究COPNA-BMI预聚树脂的固化工艺;采用TG-DTG研究了COPNA-BMI共聚树脂的热行为。研究表明,预聚树脂具有良好的流变性能,其固化反应平稳易于控制;共聚树脂具有优良的耐热性,经后处理过的固化树脂其热分解起始温度为450℃。The condensed polynuclear aromatic （COPNA） resin was synthesized using 1-naphthol as monomer and 1, 4-benzenedimethanol as crossing-linking agent in the presence of p-toluene sulfonic acid, and then allylated to prepare the allylic COPNA resin having the copolymerization reactivity with 4, 4＇-bismaleimidodiphenyl methane （BMI） to obtain high performance resin. Properties and preparation of the copolymer resin of allylie COPNA resin and BMI were studied in this paper. The chemical structures and rheological properties of the prepolymer were characterized by FT-IR and viscometer, respectively. The curing reaction of the prepolymer was studied by DSC. Moreover, TG-DTG was employed to study the thermal behavior of the copolymer resin. The results show that the prepolymer has good rheological properties and can be easily controlled during the curing reaction. Furthermore, the cured copolymer resin has good thermo-stability, as indicated by that its initial decomposition temperature arrives at 450 ℃ and the carbon yield reaches 53.6 % at 800 ℃ in nitrogen.
