【摘要】 将丙烯酸丁酯、苯乙烯和丙烯酸以３０∶１５∶４的质量比运用乳液聚合法合成了新型三元共聚物Ｐ（ＢＳＡ）。当Ｐ（ＢＳＡ）与原硅酸乙酯（ＴＥＯＳ）以９∶１的质量比反应１ｈ后，所得交联Ｐ（ＢＳＡ）的拉伸强度和扯断伸长率分别达６．３ＭＰａ和５８０％。以该新型共聚物为基体，运用低温氧化聚合法合成了半互穿网络结构的新型导电复合物聚吡咯／Ｐ（ＢＳＡ）。研究了ＦｅＣｌ３用量、吸附反应时间和溶剂性质对复合物导电性能的影响。若ｍ（ＦｅＣｌ３）／ｍ（Ｐ（ＢＳＡ））＝８／９，吸附反应２４ｈ后，复合物的电导率高达２２０Ｓ·ｍ－１。更多还原

【Abstract】 A new tercopolymer P(BSA) was synthesized by emulsion polymerization with butyl acrylate,styrene and acrylic acid at the mass ratio of 30154.The tensile strength and elongation at break point of the crosslinked P(BSA) were 6.3MPa and 580% respectively when P(BSA) and TEOS(91) refluxed for 1h.A novel conductive polypyrrole/P(BSA) composite with the structure of semiinterpenetrating network was prepared by low temperature oxidative polymerization of pyrrole within the crosslinked P(BSA) matrix.The effects of the amount of FeCl3 ,the absorptive reaction time and the nature of solvents in which pyrrole was dissolved on conductive property of the composite were studied.The conductivity of the composite is up to 220 Sm-1 when the mass ratio of FeCl3/P(BSA)=8/9 and reacted for 24h.更多还原
