聚(2-甲氧基-5庚氧基)亚苯基亚乙烯的合成及其热稳定性研究

Study on the Synthesis and Thermal Stability of Poly\=(2methoxy5heptoxy)pphenylenevinylene

用甲氧基苯酚、Ｃ７Ｈ１５Ｂｒ为原料，合成１－甲氧基－４－庚氧基苯（ＭＯＨＰＯＢ），ＭＯＨＰＯＢ氯甲基化得到１，４－双氯甲基－２－甲氧基－５－庚氧基苯（ＢＣＭＭＯＨＰＯＢ），ＢＣＭＭＯＨＰＯＢ用脱ＨＣｌ法合成可溶性聚（２－甲氧基－５－庚氧基）亚苯基亚乙烯（ＰＭＯＨＰＯＰＶ），同时对产物的热稳定性进行考察，结果表明：ＰＭＯＨＰＯＰＶ的热稳定性良好。

When pmethoxyphenol was reacted with H(CH\-2)7 Br, 1methoxy4heptoxybenzene (MOHPOB) was obtained. The chloromethylation of MOHPOB produced 1,4bis(chloromethyl)2methoxy5heptoxybenzene(BCMMOHPOB).The elimination of HCl in BCMMOHPOB produced soluble poly(2methoxy5heptoxy)pphenylenevinlylene(PMOHPOPV),its thermal stability was measured.The result showed it had good thermal stability.\=
