| 摘 要： | 通过自由基聚合反应,在淀粉分子链上接枝苯乙烯（St）、丙烯酸丁酯（BA）和N-羟甲基丙烯酰胺（HMAM）单体,合成了一种淀粉接枝表面施胶剂。探讨了过硫酸铵、引发剂和单体用量对施胶效果的影响。结果表明,其最佳合成工艺条件是：过硫酸铵用量为5%,m（FeSO4）/m（H2O2）为0.03,m（单体）/m（淀粉）为2,m（St）/m（BA）为3,HMAM用量为3%。当施胶浓度为0.09%,硫酸铝用量为0.3%时,施胶度可达60s。

| Abstract: | The starch grafted surface sizing agent was synthesized through free radical polymerization, by using styrene（St）, butyl acrylate（BA） and Nhydroxymethyl acrylamide（HMAM） as graft monomers. The effects of the dosage of ammonium persulfate, initiator and monomer on surface siz-ing were studied. The optimum synthesis conditions are as follows： the dosage of ammonium persulfate being 5%, m（FeSO4）/m（H2O2） being 0.03, m（monomer）/ m（strach）=2, m（St）/m（BA）=2, and HMAM dosage being 3%. The sizing degree is more than 60 seconds when the sizing content is 0.09% and the dosage of aluminum sulphate is 0.3%. |
