摘　　要：以苯乙烯(St)和甲基丙烯酸甲酯(MMA)为主单体、偶氮二异丁基脒盐酸盐(AIBA)为引发剂,加入少量双子乳化剂C16H31N+(CH3)2(CH2)6N+(CH3)2C16H31].2Br(-G16-6-16)和阳离子功能性单体甲基丙烯酰氧三甲基氯化铵(DMC),采用常规乳液聚合法制备了稳定的纳米阳离子聚合物乳液,探讨了G16-6-16和DMC用量对St/MMA纳米阳离子乳液聚合的影响。结果表明:随着G16-6-16用量和DMC用量的增加,乳胶粒子的粒径减小,所得的乳液是性能优良的纸张表面施胶剂。The St/MMA nano cationic emulsion was synthesized by conventional emulsion polymerization method with AIBA as initiator and C16H31N^＋（CH3）2（CH2）6N^＋（CH3）2C16H31]·2Br^-（G16-6-16）as surfactant. The effect of G16-6-16and DMC on nano cationic emulsion was investigated. The results show that the latex particle size decreased with the G16-6-16 and DMC amount increasing. This emulsion is good sizing agent for paper.
