摘　　要：通过乳液聚合方式,合成了苯乙烯-丙烯酸丁酯-乙烯基三乙氧基硅氧烷三元共聚物,作为固相微萃取涂层.采用红外光谱(IR)和紫外光谱(UV)相结合的方法,测定了单体的质量分数,并测试了该聚合物的物理性能.使用微量进样器和不锈钢毛细管自制了萃取装置,对水中小分子烷基苯、氯苯、硝基苯进行了实取试验.结果表明,自制的苯-丙-硅三元共聚物作为固相微萃取涂层热稳定性好,与石英纤维的结合力强;对水中小分子烷基苯、氯苯、硝基苯萃取效果优于商品PDMS涂层及PA涂层的萃取效果.In the paper, phenylethylene-butyl acrylate-vinylTriethoxy siloxane terpolymer, as SPME coating, was synthesized by emulsion poly merization. Combining infrared spectrum and ultraviolet spectrum, the contents of the monomers were determined. The SPME equipment was made by using microinjector and stainless steel capillaries. The coating was applied to detect and analyze alkyl aromaticses, chlorbenzenes and nitrobenzenes in water. The data determined showed that the thermal stability of the polymer coating and adhesion with fiber both were good. The extracting behavior of the polymer coating was better than commercial coatings of Polydiemthylsioxane and polyacrylate.
