摘　　要：将烷基双烯酮二聚体(简称AKD)与PAM的Hofman降解产物聚乙烯胺(PVAm)共混,制备一种具有较好乳化和分散能力的施胶剂。在中性施胶条件下,PVAm/AKD共混物用量为0.3%时,施胶度可达到32s,熟化后则可达到55s,且施胶后纸页各项强度指标均明显增加。A sizing agent with preferable emulsifying and dispersing performances was prepared by blending alkyl diketene dimer （AKD） with PVAm, a Hofman degradative product of PAM Under the neutral sizing condition, when the PVAm / AKD mixture dosage was 0.3%, the sizing degree could reach 32 s, and could reach 55 s after curing, with the various strength targets of paper increased remarkably after sizing.
