摘　　要：为了提高聚丙烯(PP)无纺布的吸收性能,通过在异丙醇/水混合酸性溶液中紫外辐照诱导的方法,成功将丙烯酸、甲基丙烯酸甲酯单体接枝到PP基体上。利用傅里叶红外转变光谱和X-射线光电能谱仪对接枝改性前后PP无纺布基体表面的化学组成进行了表征,并以原油为被吸附有机物考察了PP无纺布接枝前后的吸油性能及原油吸附影响因素。分析了PP-g-(AA+MMA)制备过程中影响因素,并对其进行了热稳定性测试、DSC分析,以及物理机械性能及重复性测试。In order to improve the absorption of polypropylene （PP） non- woven, by UV radiation- induction in isopropanol/ water mixed acid solution, successfully grafted acrylate, methyl methacrylate monomer to PP matrix. Using fourier transforminfrared spectroscopy and X-ray photoelectron spectroscopy,the chemical composition of PP non-woven before and after grafting were characterized. Using crude as adsorbed organic compound, the suction performance and influence factors were inspected. Factors influencing PP- g- （AA＋ MMA） preparation were analyzed, and thermal stability test, DSC analysis, physical and mechanical properties and repeatability test were conducted.
