摘　　要：为提高接枝变性淀粉浆料的性能,研究接枝单体的加入量和种类对接枝变性淀粉的接枝性能和上浆性能的影响。在5%~30%范围内通过改变单体加入量和种类,如应用丙烯酸甲酯、甲基丙烯酸甲酯、丙烯酸乙酯、甲基丙烯酸乙酯、丙烯酸丁酯、甲基丙烯酸丁酯等种类接枝单体,比较分析接枝变性淀粉的接枝指标和上浆性能指标。研究结果表明：制取适合涤纶上浆的接枝变性淀粉浆料,接枝单体选用丙烯酸乙酯为佳,单体加入量为20%时,接枝变性淀粉的接枝指标和综合上浆性能较好。In order to variety of monomers on improve the performance of grafting modified starch size, the effect of the amount and grafting and sizing performances of the grafted starch size are investigated by varying the dosage of monomers at the range of 5 % - 30 % and using different kinds of monomers such as methyl acrylate, methyl methaerylate, ethyl acrylate, ethyl methacrylate, butyl acrylate, and butyl methacrylate. The results show that ethyl acrylate used as grafting monomer is better and the optimum concentration of monomer is 20 % when the grafted starch is to be applied for polyester sizing and good results can be expected.
