| Abstract: | In this paper, the graft copolymerization with acrylic acid of polyurethane film initiated by eerie salt was investigeted. It was found that the structure of extender for polyurethane has a significant effect on the grafting level. The grafting level corresponds to the following order of extender, aliphatic diol>aliphatic diamine< aromatic diamine. Furthermore, the existance of layer structure of the grafted film was verified by dynamic and static mechanical tests. The hydrophilibility of the grafted polyurethane was much enhanced and the blood compatibility of that was also improved to some extent. |
