摘　　要：采用半连续种子乳液聚合的方法制备了一种具有核壳结构的松香树脂改性PVC地板胶用丙烯酸酯聚合物乳液,讨论了松香树脂质量分数、松香树脂加入方式、核壳质量比等因素对聚合物乳液性能的影响。结果表明,当松香树脂质量分数为2%,核壳单体的质量比为1∶2时,乳液的初黏性(#33)达到1.3 cm,粘接强度达到0.32 MPa。The rosin modified acrylate latex with the particle of core-shell structure for PVC floor adhesives was synthesized by seeded semicontinuous emulsion polymerization. The effect of the amount of rosin and its addition style, and the proportion of core and shell monomers on the properties of the latex was studied. When the amount of rosin was 2% and the mass ratio of core/shell monomers was 1：2, its initial tack（#33） was 1.3 cm and cohesive strength was 0.32 MPa.
