摘　　要：以2种季铵型木薯阳离子淀粉为原料，按不同的比例加入纸浆中抄纸，通过对比2种淀粉对纸浆及纸张物理性能的作用效果来确定阳离子淀粉的取代度对纸张物理性能的影响。结果表明：高取代度的阳离子淀粉对提高纸浆留着及纸张的物理性能最有效，且2种淀粉的添加量分别为纸张定量的1．0％时，对纸张的增强效果最好。Two kinds of quaternary ammonium cationic starch were added into the pulp with different proportion. Comparing the properties of the pulp and paper with different starch, it was found that the degree of substitution of cationic starch greatly affects the paper properties. The cationic starch with a high degree of substitution was good at improving the pulp and paper physical properties, and when the dosage was 1.0%, the paper could be obtained with the greatest strength enhancement.
