This article plays emphasis on the effects of monomer solution ingredients on he grafting yield. The results show that grafting yield and exchange capacity can be 0%~95% and 2 mmol/g~6 mmol/g (dry sample) by using aceton, water as thinner monomer concentration: 1 mol/L~7 mol/L), benzophenone as photosensitizer, a proper quantity of AIBN as subsidiary initiator. The structures and properties of the PP fibers were also studied. Pictures of SEM, optical microscope and IR spectrum showed the istributions and lengths of AA branches on PP nov-woven before and after grafting. The mark of metallic grid on the PP suggested that polymerization inhibition was caused by the lightshade. ictures of infrared absorption spectrum provided the process of UV grafting polymerization with reliable evidences.
