【摘要】 研究了木薯淀粉经碱糊化后,以KMnO₄为引发剂,在酸性介质中与丙烯腈的接技共聚。结果表明,单体转化率高,接技效率达95％,支链分子量达30万。接技共聚物在碱溶液中的水解产物吸水能力可超过自重的2000倍。更多还原

【Abstract】 Graft copolymerization of AN onto cassava starch gelatinized by alkali at room tempe-rature has been studied using KMnO₄ as initiator in acid solution. Resu t showed highmonomer convertion to polymer （80%）, very high graft efficiency （95%）, and high mole-cular weight of graft polymer （3×10⁵）. The hyorolyzate of graft copolymer can absorb upto over 2000 times of water （g/g）.更多还原
