2-Sulfoethyl Methacrylate, or 2-SEM, is a functional monomer which combines a highly reactive vinyl group with a sulfonic acid group. The unique properties of the sulfonic acid group make 2-SEM useful in many applications
2-SEM is an efficient emulsion stabilizing comonomer, which when used in low concentrations of 1 - 2 %, results in the formation of polymer dispersions that exhibit excellent stability to shear and compounding. The use of 2-SEM allows for substancial reduction in the level of conventional emulsifiers in emulsion polymer formulations. 2-SEM stabilized formulations are free of high concentrations of non volatile and migratory surfactants. Thus, 2-SEM promotes adhesion of polymers to various metals, thermoplastics and, to a lesser degree, glass.
