以对甲氧基苯酚和溴壬烷为原料 ,经过醚化和双氯甲基化反应得到 1 ,4 -双 (氯甲基 ) - 2 -甲氧基 - 5-壬氧基苯 ( BCMMONOB) ,BCMMONOB在强碱作用下通过脱氯化氢得到可溶性的聚 ( 2 -甲氧基 -5-壬氧基 )对苯乙炔 ( PMONOPV) ;首次采用脱氯化氢消除反应实现了 BCMMONOB与 1 ,4 -双 (氯甲基 ) - 2 ,5-二甲基苯 ( BCMDMB)共聚。讨论了两种单体结构和縻尔比率及溶剂因素对聚合反应和共聚物溶解性的影响 ;探讨了脱氯化氢消除反应机理。对聚合物的结构进行了 IR,1H NMR和 UV/Vis表征。
Using p - methoxyphenol and bromononane as raw materials, 1, 4 - bis (chloromethyl) -2 - methoxy - 5 - nonyloxybenzene (BCMMONOB) was obtained by etherification and bischloromethylation. , BCMMONOB can get soluble poly (2-methoxy-5-nonyloxy) p-phenylacetylene (PMONOPV) through dehydrochlorination under the action of strong base. The first reaction of BCMMONOB with 1, 4 - bis Chloromethyl) -2,5-dimethylbenzene (BCMDMB). The effects of two kinds of monomer structure and molar ratio and solvent factors on the polymerization and copolymer solubility were discussed. The mechanism of dehydrochlorination elimination was discussed. The structure of the polymer was characterized by IR, 1H NMR and UV / Vis.
