Fund Project: The National Natural Science Foundation of China (Grant No. 29774036, 59773019 and 29904007) and PPLAS Foundation of the Chinese Academy of Sciences are acknowledged for their financial supports. The discussions among International Center of Polymer Gel are helpful to this paper, especially that with Dr. Mingming Guo (Univ. of Akron), Dr. Zhibing Hu (Univ. of North Texas).

The overall cross-linking copolymerization of acrylic acid and multi-armed cross-linkers are investigated by in situ interferometry. The results show that the more arms the cross-linkers have, the higher the polymerization rate is. However, they also mean the existence of less cross-linking efficiency and some defects in gel network.
