以红薯淀粉为原料、N，N-亚甲基双丙烯酰胺（MBAA）为交联剂、Span-60和 Tween-60为乳化剂、环己烷和三氯甲烷为油相、硝酸铈铵为引发剂，采用反相悬浮聚合法制备红薯淀粉交联微球，分别采用傅立叶变换红外光谱仪和扫描电子显微镜表征了其结构和形貌，通过单因素实验确定红薯淀粉交联微球的最佳制备条件为：淀粉溶液浓度10％、MBAA用量0.4 g、油水比5∶2、引发剂用量0.25 g。
以紅藷澱粉為原料、N，N-亞甲基雙丙烯酰胺（MBAA）為交聯劑、Span-60和 Tween-60為乳化劑、環己烷和三氯甲烷為油相、硝痠鈰銨為引髮劑，採用反相懸浮聚閤法製備紅藷澱粉交聯微毬，分彆採用傅立葉變換紅外光譜儀和掃描電子顯微鏡錶徵瞭其結構和形貌，通過單因素實驗確定紅藷澱粉交聯微毬的最佳製備條件為：澱粉溶液濃度10％、MBAA用量0.4 g、油水比5∶2、引髮劑用量0.25 g。

Using sweet-potato starch as raw material,N,N-methylenebisacrylamide(MBAA)as crosslinking agent,Span-60 and Tween-60 as emulsifying agents,cyclohexane and chloroform as oil phases,ammonium ceri-um nitrate as initiator,the sweet-potato starch crosslinking microspheres were prepared by inverse suspension polymerization.The structure and morphology of the starch microspheres were characterized by FTIR and SEM,respectively.The optimum preparation conditions were obtained by single factor experiment as follows:the concentration of starch solution 5%,the amount of MBAA 0.4 g,the volume ratio of oil to water 5∶2,the amount of initiator 0.25 g.
