The preparation method comprises monomer synthesis and polymer synthesis. The polymer synthesis is that cyclopentadienyl sodium monomer is added into metallic cobalt complex-triphenyl phosphorus cobalt chloride under strict oxygen-free and water-free conditions, and then double inner alkyne or outer alkyne conjugate monomer is added in, and after reaction, the precipitation, filtering, abstersion and vacuum-drying are carried out, the large molecules polymer containing cyclopentadienyl cobaltocenium organometallic cobalt is obtained.

The area ratios of 980/1022, 980/1047,(980+1047)/1022 and 980/(1022+1047) cm^(-1) were decreased as the degree of acetification increased which indicated that acetification induced a decrease of crystallinity of starch. And the crystal structure changed from A-type to V-type. For the cross-linking of POCl3, the area ratios of 980/1022, 980/1047,(980+1047)/1022 and 980/(1022+1047) cm^(-1) were also decreased as the degree of cross-linking but the decrease was little compared to that of acetification. The result indicated that cross-linking of POCl3 had little effect on the starch crystal structure.

随着醋酸酯化取代度的增大，980/1022、980/1047、(980+1047)/1022和980/(1022+1047)的相对峰面积的比值均呈现下降趋势，表明醋酸酯化改性会导致淀粉结晶程度降低，结晶形态从A型转变为V型；随着交联度的增大，980/1022、980/1047、(980+1047)/1022和980/(1022+1047)的相对峰面积比值均呈现下降趋势，但下降程度较小，表明三氯氧磷交联对淀粉结晶结构影响不明显。
