摘　　要：采用预乳化、半连续种子聚合法工艺,通过St-BA-MMA-AA四元共聚,研制出了具有核壳结构的苯丙乳液,并以此配制成外墙涂料。着重讨论了乳化剂和丙烯酸的用量,以及核中不同单体用量比对涂料性能的影响,同时用MDSC及IR表征了所得聚合物乳液的结构。The styrene/acrylic emulsion of St - BA - MMA - AA four - component eopolymerization has been prepared by using pre - emulsion and semi - continuous seed polymerization technology. On the basis of this, an exterior wall paint has been made. The paper was focused on discussion about the influence of dosage emulsifiers and acrylic acid, and the monomer ratio in the ' core' to the paint performance. In the meantime, the structure of the emulsion has been characterized by MDSC and IR.
