研究了乳胶粒径、表面阳离子量不同的NVF-SM-DMDAAC共聚物（PNSD）乳液在碱性条件下对桉木浆纸张的增强作用。结果表明：PNSD的纸张增强效果随乳胶粒径的减小而增强，与表面阳离子量和添加量呈正相关，其中粒径最小的PNSD-C1在添加量为0.25%时，纸张干、湿抗张指数和环压指数分别增大18%、54%和26%；表面阳离子量大的PNSD-P4在添加量为0.25%时，可使纸张干、湿抗张指数和环压指数分别增大23%、49%和33%。

The strengthening to Eucalyptus pulp was studied of NVF-SM-DMDAAC copolymer emulsion (PNSD) with different particle size and surface cationic charge. The results show that the strengthening performance increases with the decrease of the emulsion particle size, having a positive correlation with the surface cationic charge and adding dosage. When the adding dosage of PNSD-C1 with the smallest particle size is 0.25%, the paper dry tensile index, wet tensile index and ring crash index are raised by 18%, 54% and 26% respectively; when the adding dosage of PNSD-P4 with the largest surface cationic charge is 0.25%, the paper dry tensile index, wet tensile index and ring crash index are raised by 23%, 49%and 33%respectively.
