Emulsifier-free Emulsion Polymerization Participated by KPS-CuSO4-Na2SO3

Abstract

Abstract: Rapid emulsifier-free emulsion polymerization of methyl methacrylate-styrene was discussed in the presence of redox initiator KPS-CuSO<-Na₂SO₃. When [MMA]=0.51 mol/L, [St] = 0.49 mol/L, temp.70℃, more suitable quantity of redox initiator was obtained: [KPS]=2.77× 10^-3 mol/L, [CuSO₄]=l.50×10^-5 mol/L, [Na₂SO₃]=2.77×10^-3 mol/L.Reaction time was 100 min.Under the conditions as indicates above, the conversion of monomers surpassed 90%.Restrictive aggregation of emulsion particles existed in the process of reaction.Molecular weight and its distribution of emulsion which were produced by three system of emulsion polymerization are discussed.According to Arrheniu's figuration, the activation energy of polymerization (E_a = 81.6 kJ/mol) was counted.The reaction rate constant k_p=321.9 L/mol·s) at 70℃ was calculated.

Key words: Emulsifier-free emulsion polymerization, Methyl methacryiate, Styrene, Redox initiator
