In this study, we first synthesize a conducting polymer, P3HT, via Grignard metathesis method. And we functionalize the polymer chain end of P3HT into vinyl group. After characterize from 1H NMR spectroscopy, we use the end functionalized P3HT to proceed coupling reaction with P2VP anion.

为了达到这个研究目的，我们先利用格林纳置换法合成导电高分子P3HT，并将其尾端乙烯化，在经核磁共振仪确定结构后，利用此尾端乙烯化之P3HT与P2VP阴离子反应进行接合。

The Stille coupling reaction between 8 iodo 9 benzyl 9H purine and RSnBu 3 (R=vinyl,2 thienyl,2 furyl,phenylethynyl and phenyl) was studied using (Ph 3P) 2PdCl 2 as catalyst and DMF as solvent.

采用 (Ph3 P) 2 PdCl2 为催化剂，DMF为溶剂，对 8 碘 9 苄基 9H 嘌呤与有机锡试剂RSnBu3 (R=乙烯基、2 噻吩基、2 呋喃基、苯乙炔基和苯基等)之间的 Stille偶合反应进行了研究，合成出了5种 8位取代的嘌呤衍生物。

The Solidification temperature range was defined as 110-200℃ by DSC analysis. More accelerant used can increase the casing samples dynamic performance, but more than enough accelerant can induce a severe solidified reaction that result in a smaller polymeric meshwork and reducing the sample's performance. Normally the Accelerant dosage can be 2 portions; The Epoxy resin CFRP has a obvious better performances than the Vinyl-ester Resin CFRP, i.e. had a Bend Strength of 1516MPa, LSS of 85MPa, also Tg raised to 195~C~ When used the end-carboxyl polyether to reinforce the epoxy resin, the casing sample's SS, BS and Crack Elongation all increased geminately. The CFRP performance also increased a little, that is because the performance of the CFRP mainly contributed by the CF. The reinforced resin improved the interface between the CF and resin that contribute to the little increasing.

通过DSC分析确定了该环氧树脂的固化温度范围为110~200℃，促进剂增加会提高浇注体力学性能，但过多的促进剂会使固化反应剧烈，聚合网络减小，使浇注体性能下降，一般用量为2份左右；以环氧树脂为基体的复合材料性能明显比以乙烯基酯树脂的性能提高，弯曲强度达到1516MPa，层间剪切强度达到85MPa，同时Tg也上升到195℃；用端羧基聚醚增韧环氧树脂后，其浇注体的拉伸强度、弯曲强度及断裂伸长都成倍增加，复合材料的性能也有所提高，但提高幅度不大，因为复合材料的力学性能主要由碳纤维承担，树脂增韧后改善了复合材料的界面性能。
