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。
A novel terpolymer P (BSA) was synthesized by emulsion polymerization from butyl acrylate, styrene and acrylic acid at mass ratio of 30:15:4. The tensile strength and elongation at break of the obtained cross-linked P (BSA) reached 6.3 MPa and 580%, respectively, when P (BSA) reacted with TEOS at a mass ratio of 9: 1 for 1 h. . Based on this new copolymer, a novel conductive composite polypyrrole / P (BSA) with semi-IPN structure was synthesized by low temperature oxidative polymerization. The effects of FeCl3 dosage, adsorption reaction time and solvent properties on the electrical conductivity of the composites were investigated. When the molar ratio of FeCl3 / m (P (BSA) = 8/9), the conductivity of the composite reached as high as 220S · m-1 after 24h adsorption.
