The results show that the hydrogen bond is the main force between β-cyclodextrin and bilirubin. After the adsorption of bilirubin for 2 h, the adsorption capacity is over 90 %.展开更多

Polymer ofGMA with planned molecular weight and narrow molecular weight distribution was obtained. In caseof bulk polymerization with the same initiator and catalyst the molecular weight of the polymerobtained was 1.5~2. 1 times greater than that of the above one. By using 1-phenylethyl chloride(PECl)/CuCl/BPY as catalyst controlled ATRP of GMA has failed whether it was in bulk or insolution.展开更多
