| Abstract: | A series of amphoteric polyacrylamide resins(APAMR)was synthesized by means of aqueous polymerization with acrylamide(AM)and acrylic acid(AA)and dimethyldiallyl-ammonium chloride(DMDAAC)as raw materials,potassium persulfate as initiator and N,N-methylenebisacylamide(MBAM)as crossing agent.The effect of APAMR on paper strength and filler retention was discussed in this paper.The result of experiment showed that paper breaking length,burst index and filler retention increased12.88%,16.15%and18.51%respectively when0.45%APAMR-28(based on oven-dried pulp)was added in wheat straw pulp. |
