摘要: 利用对溴苯乙烯与苯乙烯的自由基共聚反应成功制备了溴掺杂CH聚合物靶材料，溴原子的原子分数通过对溴苯乙烯和苯乙烯的投料比调节，已经合成了溴代原子分数0.6%~4.2%的掺溴靶材料。通过热重和凝胶渗透色谱仪测试了薄膜的热分解温度和聚合物的分子量，聚合物的热分解温度达到385 ℃，重均分子量达到41.5万，由其通过浇铸法制备的调制薄膜具有很好的韧性。Abstract: This paper presents a simple method for the preparation of brominated target materials. These materials were obtained by copolymerization of different ratio of p-bromostyrene and styrene, and the brominated composition was measured from 0.6% to 4.2%. Moreover, these copolymer materials had good thermal stability with high decomposition temperatures (385 ℃) and high molecular weight. Furthermore, the films prepared from these materials showed excellent toughness.
