Abstract

The aim of this work is to prepare polystyrene latex functionalized with phosphonate groups using the surfactant methacrylic monomer, Sodium methyl-11-methacryloyloxyundecylphosphonate (MP11). To assess the possibility of incorporation of the MP11 in polystyrene, we determined its report Kp2/KTe. The kinetics were performed under the same conditions as those with styrene that is to say, taking potassium persulfate (K2S2O8) as initiator and a temperature T = 70°C. The kinetics of disappearance of monomer MP11 was developed. The evolution of monomer concentration versus time allowed to access the value of Kp2/KTe = 0,261 L. mol-1.s-1. This value is quite comparable to those of similar structures monomers. Lauryl and cetylmethacrylate have values Kp2/KTe equal to 0,353 and 0,563 L. mol-1.s-1 respectively. The results show that our MP11 can be used for the preparation of latex of polystyrene functionalized with phosphonate groups.
