| 摘 要： | 利用原子转移自由基聚合合成了端羧基聚苯乙烯,然后与4-氨基苯乙酮反应,生成末端为乙酰基的聚合物,以P2O5为催化剂,将功能化的聚合物与5-乙酰基-2-氨基二苯甲酮共聚,合成出刚柔嵌段共聚物聚苯基喹啉-b-聚苯乙烯(PPO-b-PS),用红外光谱(IR)、氢核磁共振(1HNMR)和热重分析(TGA)对其结构和性能进行了表征,并在三氟乙酸／二氯甲烷混合溶剂中进行了初步的自组装研究。

| Abstract: | Polystyrene telechelic prepolymer with carboxyl group terminated was synthesized by the atom transfer radical polymerization (ATRP),and the carboxylic acid terminated polystyrene (PS-COOH) was functionalized by reacted with 4-aminoacetophenone and the ketone methylene-terminated polystyrene obtained.Rod-coil block copolymers of poly(phenylquino-line)-b-polystyrene(PPQ-b-PS) was synthesized by the copolymerization of 5-acetyl-2-aminobenzophenone with the functionalized polystyrene by P2O5 as catalyst.The structure and properties of PPQ-b-PS diblock copolymers were characterized by IR, 1HNMR, TGA, and the self-assembling behavior of the copolymers in the mixed solvent of trifluoroacetic acid/ dichloromethane was studied elementarily. |
