Polymer antistatic agent polypropylene grafted styrene sulfonic acid to compounded polyaniline (PP-g-StS-PANI) was prepared by solution grafting polymerization to dodecylbenzene sulfonic acid, p-toluenesulfonic acid, acrylic acid as dopant and the polyaniline was compounded to the PP macromolecular chain by the sulfonic acid group adsorption. The polymer antistatic agent was characterized by FTIR. Influence factors of properties of polymer antistatic agent were studied. The results showed that the DBSA doped acid-prepared anti~static agent was the best. The complex efficient and antistatic effect of composite was the best when mdoped acid/mPP-g-StS=15:1,nAPSANI=2:1, and the volume resistivity of PP-g-StS-PANI/PP down to 1012Ω· cm. PP blend were tested by means of SEM and DSC, which showed that blends was good compatibility.%分别以十二烷基苯磺酸、对甲苯磺酸、丙烯酸为掺杂剂采用溶液聚合方法,通过磺酸基团作用将聚苯胺复合到PP大分子链上,制备了高分子永久型抗静电剂聚丙烯接枝苯乙烯磺酸复合聚苯胺(PP-g-StS-PANI).利用FTIR对高分子抗静电剂进行表征.研究了影响高分子抗静电剂制备及性能的因素.结果表明,以十二烷基苯磺酸为掺杂酸制备的抗静电剂效果最好,当m掺杂酸/mPP-g-StS=15/1,nAPsANI=2时,复合效率最高,抗静电效果最好,抗静电剂与PP共混物体积电阻率下降到1012Ω·cm.通过DSC分析及SEM对PP共混物界面进行分析,共混物具有良好的相容性.
