摘　　要：采用种子乳液聚合方法合成了聚丙烯酸丁酯(PBA)/聚(甲基丙烯酸甲酯-衣康酸)[P(MMA-ITA)]核壳乳胶粒子,并用透射电子显微镜、傅里叶变换红外光谱仪、差示扫描量热仪及非水酸碱滴定等对其进行了表征。结果表明:核壳乳胶粒子平均粒径为330nm,其中,PBA核平均粒径为290nm;通过接枝共聚物P(MMA-ITA)实现了核壳间的化学键连接。Poly（n-butyl acrylate）/poly（methyl methacrylate-itaconic acid） [PBA/P（MMA-ITA）] latex particles with core-shell structure were synthesized via seeded emulsion polymerization process. The latex particles were characterized by means of transition electron microscop（TEM）, Fourier transform infrared spectroscopy （FTIR）, differential scanning calorimetrer（DSC） and non-aqueous acid-base titration. The results show that the average size of latex particles is 330 nm, in which the average size of core PBA is 290 nm. Moreover, the chemical connection between the core and shell layer is achieved through the graft copolymer P（MMA-ITA）.
