摘　　要：报道了一种新型的含有苯并环丁烯基团的热固性芳香族聚碳酸酯的合成方法.该聚合物具有良好的溶解性,可用溶液法进行加工.该聚合物在高温固化后表现出优异的热稳定性,在氮气中5%的热重损失温度高达451℃,在1000℃下的残炭率为33%.该聚合物还具有良好疏水性,在沸水中浸泡24 h后的吸水率低至0.21%.为了进一步研究苯并环丁烯基团的引入对芳香族聚碳酸酯性能的影响,利用双酚A单体合成了部分侧链带有苯并环丁烯基团的共聚物以及线性双酚A型聚碳酸酯.通过性能对比研究可知,苯并环丁烯基团的引入能有效提高芳香族聚碳酸酯的耐热性和疏水性.A novel benzocyclobutene （BCB）-functionalized polycarbonate was synthesized. This polymer showed good solu-bility in organic solvents and could be processed by solution method. After cured at high temperature, the polymer exhibited high thermostability with 5% weight loss temperature of 451℃ and a char yield of 33% at 1000℃ in nitrogen. The cured polymer showed good hydrophobicity with water uptake of 0.21% after immersion in boiling water for 24 h. Moreover, a copolymer and poly（bisphenol A carbonate） were synthesized by bisphenol A monomer to study the influence of the existence of BCB groups on the properties of the aromatic polycarbonate. The results of comparative study showed that BCB groups can effectively improve the thermostability and hydrophoblicity of aromatic polycarbonates.
