Abstract In order to obtain suitable formulation of designing direct synthesis of acrylic polymer emulsions to be used as EPSA, having high shear resistance together with high peel strength and tack, free radical emulsion polymerization of hard monomers, such as styrene( St), vinyl acetate( VAc), methyl methacrylate( MMA) and butyl methacrylate( BMA), and soft monomers, butyl acrylate( BA) and 2- ethylhexyl acrylate( 2_EHA) along with multifunctional monomers, namely acrylic acid( AA), were carried out and an optimized composition of the acrylic monomers, 69 parts BA, 25 parts VAc, 5 parts BMA and 1 parts AA which are all in terms of the total weight of the monomers was obtained. For the investigation of the Effect of 2-EHA as a soft monomer on the adhesion properties of PSAs, the effect of varying the n-BA/2-EHA monomer composition on the adhesion performance of optimized PSA was investigated in terms of tack, peel and shear resistance, stability of emulsion latex, and its appearance. a decrease in the peel strength was observed although still having high peel strength when the 2-EHA content was increased to more than 50%. When the 2-EHA content increased to more than 50%wt, the peel strength was retained at a constant level.
