摘要
以硝酸铈铵为引发剂,合成了氧化淀粉及可溶性淀粉等变性淀粉与丙烯酰胺的接枝共聚物,详细考察了引发剂用量及淀粉性质对单体转化率和接枝率的影响。结果发现,用氧化淀粉,可溶性淀粉等变性淀粉与丙烯酰胺接枝共聚,可获得比原淀粉高得多的单体转化率和接枝率。在瓦楞纸中的使用表明,添加0.5%的氧化淀粉—丙烯酰胺接枝共聚物可使瓦楞纸的环压强度增加52%。
The graft copolymerization of acrylamide onto modified starches, such as oxidized starch and solubilized starch, initiated by ceric nitrate, was carried out. The effect of the concentration of initiator and the property of starch on the conversion of monomer and graft ratio were studied in detail, The results showed that a higher conversion of monomer and graft ratio could be obtained when oxidized or solubifized starches were used in the graft copolymerization than when rude corn starch was used. It was found that when 0.5% oxidized starch-acrylamide graft copolymer was added to the polymer, the ring-crush strength of the corrugated paper increased by 52%.
