阳离子淀粉接枝窄相对分子质量阴离子聚丙烯酰胺制备干增强剂

Preparation of Dry-strength Agent via Grafting Cationic Starch with APAM of Narrow Molecular Weight Distribution

用阳离子淀粉接枝窄相对分子质量阴离子聚丙烯酰胺制备干增强剂。通过探索性实验,所合成出来的产品具有用量少,增强效果好等特点。

The graft copolymer of cationic starch and APAM with narrow molecular weight distribution was prepared and used for dry-strengthening agent. The product synthesized in laboratory was proved to have the advantages of high strengthening effect and low effective dosage.
