1,4-双(氯甲基)-2-甲氧基-5-壬氧基苯的均聚和共聚研究

Study on the Synthesis of Monopolymer and Copolymer of 1.4-Bischloromethyl-2-methoxy-5-nonoxybenzene

以１，４－双（氯甲基）－２，５一二甲基苯（ＢＣＭＤＭＢ）和１，４－双氯甲基－２－甲氧基－５－壬氧基苯（ＢＣＭＭＯＮＯＢ）为单体，采用脱氯化氢法，合成了聚（２，５－二甲基）对亚苯基亚乙烯（ＰＤＭＰＶ）和聚（２－甲氧基－５－壬氧基）对亚苯基亚乙烯（ＰＭＯＮＯＰＶ）；并对ＢＣＭＤＭＢ和ＢＣＭＭＯＮＯＢ的共聚进行了研究。结果表明，适宜的反应条件为：碱与单体的摩尔比为２０∶１，在室温下聚合时间为３０ｈ，碱的ｐＨ＝１４时产率最高。用ＩＲ、１Ｈ－ＮＭＲ、ＵＶ—Ｖｉｓ对聚合物进行了表征。

1,4-Bis(chloromethyl)-2,5-dimethybenzene(BCMDMB) and 1,4-bis(chloromethyl)-2-methoxy-5-nonoxybenzene (BCMMONOB) are used as raw material to sythesize poly (2,5-dimethyl)phenylenevinylene(PDMPV) and poly (2-methoxy-5-nonoxy)phenylenevinylene(PMONOPV). The conditions of copolymerization of BCMDMB and BCMMONOB were discussed. The results show that the optimun reaction conditions are as follows: molar ratio of base to monomer is 2.0∶1 and polymerization time is 30 hours and pH=14 under room temperature. The structure of the polymer is characterized by IR, 1H-NMR, UV-Vis.
