Abstract Polymer-modified mortars using MMA/BA, MMA/EA latexes are prepared with various monomer ratios, and tested for air content, flexural and compressive strengths, water absorption and chloride ion penetration. From the test results, the water-cement ratio and the air content of polymer-modified mortars using MMA/BA, MMA/EA latexes is decreased remarkably with an increase in the polymer-cement ratio irrespective of emulsifier and monomer ratio. And, the superior flexural and compressive strengths of polymer-modified mortars using MMA/BA latexes is obtained at a bound MMA content of 80 percent and a emulsifier ratio 6 percent, MMA/EA latexes is obtained at a bound MMA content of 60 percent and a emulsifier ratio of 6 percent. Also, the water absorption and chloride ion penetration depth are greatly affected by the polymer-cement ratio rather than the bound MMA and emulsif
