摘　　要：以三偏磷酸钠为交联剂,合成了羧甲基淀粉钠/马铃薯淀粉交联微球。通过红外光谱、扫描电子显微镜以及吸水率的测定对产物进行了表征。结果表明:交联微球中羧甲基淀粉钠的含量越高,交联微球的吸水率越高。当交联剂用量为6%时,微球的形态和粒径分布最好。With sodium trimetaphosphate as the crosslinking agent, the sodium carboxymethyl starch/ potato starch crosslinking microspheres were prepared by the crosslinking reaction. The products were characterized by infrared spectra （FTIR）, scanning electron microscope and measurement of water absorption. The results show that the higher proportion of sodium carboxymethyl starch is, the higher the rate of water absorption is. When the dosage of the crosslinking agent is 6%, the morphology and size distribution of the microspheres are the best.
