摘　　要：以丙烯酰胺(AM)、甲基丙烯酰氧乙基三甲基氯化铵(DMC)和2-丙烯酰胺基-2-甲基-1-丙烷磺酸(AMPS)为单体,合成了两性聚丙烯酰胺,并用红外光谱(IR)对所合成的助剂进行了表征。测定了其对再生纤维(OCC)成纸增强效果。并采用红外光谱(IR)、示差扫描量热法(DSC)、扫描电镜(SEM)等分析手段对其增强机理进行了初步探讨。Using polyacrylamide （AM）, methyl acrylyl ethyl trimethyl ammonium chloride （DMC） and 2 - acryl- amide - 2 - methyl - 1 - propane sulfonic acid （AMPS） as emulsification monomers, a novel amphoteric reinforcing agent was synthesized. Infrared spectra analysis was adopted to feature this novel agent. And its reinforcing effect on the paper made of secondary fiber was tested. Infrared spectra analysis, differential scanning calorimetry （DSC） and scanning electron microscope （SEM） were also adopted to act as methods supporting the preliminary discussion of its reinforcing mechanism.
