摘　　要：Dicyandiamide-formaldehyde condensation copolymer was synthesized and used as a wet-end additive for papermaking.The retention of fibers and fines was used as a performance index.Factors were evaluated governing the performance of the polymer,including polymer dosage,pH and mixing time.The optimum dosage of the polymer was found to be 0.03%under the conditions.Overall,the polymer was effective in improving the drainage,as well as the retention of fibers and fines in papermaking process。

关 键 词：Dicyandiamide-formaldehyde RETENTION Drainage PAPERMAKING
