Synthesis of Rosin Modified Acrylate Latex and Its Application in PVC Floor Adhesives

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.
