摘　　要：以双酚A型氰酸酯树脂(BADCy)为主要原料,采用模塑成型法制备了氰酸酯泡沫塑料(CEF),并考查了所得泡沫的化学结构、泡孔结构、热性能和力学性能等。结果表明,体系的最佳反应条件为155℃/2 h+200℃/2 h,制得的CEF泡孔均匀,为闭孔结构;泡沫塑料的玻璃化转变温度(T_g)为263℃,失重5%的热分解温度为344℃;CEF的压缩模量和压缩强度分别与ρ^(1.043)和ρ^(2.204)存在线性关系。Cyanate ester foam（CEF） was prepared via molding foaming with bisphenol A cyanate ester resin （13ADUy） as the main material, l ne chemical structure, CCll s[rucl_uftt, behavior, and mechanical property of the foam were studied. It showed that CEF could be fully- cured under 155 ℃/2 h＋200 ℃/2 h. Closed cells were uniformly distributed. Glass transition temperature （T g） of the CEF was 263 ℃, and 5 % weight loss temperature was 344 ℃, which revealed an excellent thermal stability. CEF had excellent mechanical properties, and the compressive modulus and compressive strength had a linear relationship with ρ1.043 and ρ2.204.
