摘要
研究了利用铈盐引发丙烯腈与亚麻接枝共聚反应。FT-IR证明-CN已接到亚麻纤维上,SEM照片表明,接枝后的亚麻纤维表面有凸起而变得粗糙。X射线衍射谱图显示接枝后亚麻纤维的结晶度下降。探讨了引发剂浓度、单体浓度、接枝反应时间、温度对接枝聚合反应的影响。
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.
