| Abstract: | In this paper, the two phase structure and some related biological properties were studied by using DDV and DSG measurements. It was found that there existed some interaction between the hard segment of polyurethane and polyacrylonitrile in this polymer blend system. The results from property measurements showed that the mould resistance of the blended polyurethane was much better than that of unblended ones. After hydrolysis in basic meduim,the hydrophilibility of the blended polyurethanes was enhanced significantly, and the blood compatibility of blended polyurethanes was improved to some extent. |
