摘　　要：采用紫外辐射引发的方法,在主要利用毛细管力作用吸油的聚丙烯纤维上接枝聚丙烯酸丁酯,制备了高吸油纤维。研究了影响聚丙烯纤维接枝率的因素,如辐照时间、单体浓度、光敏剂浓度等。用衰减全反射傅立叶红外光谱对接枝前后的纤维进行了表征,结果表明丙烯酸丁酯被成功接枝到PP纤维上。随着接枝率的增大,吸油纤维对柴油的吸附量先增大后减小。当接枝率为15.5%时,对柴油的吸附倍率从原纤维的11.5g/g提高到18.3g/g。相比于聚丙烯酸脂,该吸油纤维更具备了吸附速率快的特点。The surface of polypropylene （PP） fiber was modified through grafting polymerization of butyl acry-late（BA） initiated by high energy ultraviolet （UV）. The factors influenced the grafting degree of BA were dis- cussed, such as the irradiation time, the concentration of monomer and photosensitizer. The original and grafted PP fibers were characterized by Fourier transform infrared （FT-IR） spectrometer and the results indicated that butyl acrylate was grafted onto the surface of PP fibers. With the increase of grafting degree, the adsorption ca- pacity of grafted fiber using diesel fuel as the adsorbate increased first and then decreased. When the grafting degree was 15.5% the maximum oil-absorption capacity reached 18.3g/g, while the oil-absorption capacity of PP fiber was only 11.5g/g. The adsorption rate for diesel oil was fast compared with acrylate resin.
