Abstract
Grafting polymerization of acrylic acid onto flax initiated by ceric salt has been studied. FT-IR spectrums indicate that (-CN) groups have been induced into flax. SEM image shows that grafted flax surface turns rougher and heavier. X-ray diffraction spectrums show that the crystal degree of grafted flax has turned smaller than general flax. The effects of ceric salt′s concentration, initiating time, grafiing temperature and monomer′s concentration on grafting polymerization were investigated.
