摘　　要：采用核-壳技术制备了醋酸乙烯酯-丙烯酸共聚乳液。研究了丙烯酸(AA)含量、聚乙烯醇(PVA)用量,核/壳比变化对乳液性能的影响。结果表明:改变AA含量和核/壳比,能有效调整乳液的粘度;如果用丙烯酸改性PVAc乳液,不用增塑剂,也能显著地降低乳液的最低成膜温度。Polyvinyl acetate-acrylic acid copolymerization emulsion with core/shell technology was prepared. The influences on properties of the acrylic acid（AA）content ,polyvinyl alcohol（PVA） content and the proportion of core/shell were studied. The results indicated that emulsion viscosity changes with content of AA and the proportion of core/shell,if polyvinyl acetate emulsion modified by AA without plasticizer,it can reduce the minimum film-forming temperature of emulsion obviously.
