| Abstract: | Starch sulfate with anticoagulant activity and low fluidity was prepared from potato starch by a new synthesis technology:the starch was first sulfated by sodium sulfate and sodium nitrite in a small amount of diluted sulfuric acid,then cross-linked by epichlorohydrin in water for 10-12 h.In such method,the degradation of starch is overcome,the anticoagulant activity of starch sulfate is much enhanced.Also the effects of cross-link on fluidity and anticoagulant activity of the subject was discussed. |

| Keywords: | starch sulfate cross-linked starch compound preparation |
