The sipomer Pam 100(sp100) monomer is introduced by Rodia company as adhesion promoter of lattices. In this research, an acrylic- styrene latex is synthesized. Sp100 was included in the range of 1-10% by the weight of the monomers. The other monomers were styrene methyl methacrylate (MMA), ethyl acrylate(EA) and acrylic acid(AA). Optimum contenet of sp100 was obtained at 10%. In the next step the effect of Tg on corrosion and adhesion in the absence of sp 100 was investigated using Fox equation . The best result of adhesion was obtained at Tg 30°C; and the least corrosion occurred at -10°C.In the third step of this research the synthesized lattices were neutralizeaed with different bases: NaOH, amonia and monoethanolamine then they compared with their acid form.The best adhesion and corrosion resistance was obtained by the sample which neutralized by NaoH and Ammonia respectively. Adhesion evaluated by cross cut test and corrosion was studied by salt spray under the standards ASTM D3359 and ASTM D714 respectively.
