| 摘 要： | 以Mn(H2P2O7)3]3-为引发剂,对不同来源淀粉与丙烯腈的接枝共聚反应进行了研究,考察了淀粉预处理方式对淀粉接枝共聚反应的影响.结果显示:用颗粒淀粉进行接枝共聚反应时,接枝效果受到淀粉颗粒大小的影响;用糊化后的淀粉进行接枝共聚反应时,最终制得产物的吸水率较高,并部分地依赖淀粉中直链和支链淀粉的含量.淀粉的预处理如糊化、氧化、酸解对接枝效果都有一定的影响.

| Abstract: | The grafting of acrylonitrile to different starch by manganic pyrophosphate initiation has been studied, and the effect of preatment has been also discussed. It was showed that when using granule starch as substrats, graft copolymerization was effected. When using gelatinized starch as substrate, the absorbency of final starch was high, and partially effected by amylose and amylopectin in starch. In addition, preatment of starch such as gelatinization, acid modification or oxidization could also effect the graft copolymerization. |
