Abstract
The environmental friendly polyacrylate latex was prepared by semi-continuous seeded emulsion polymerization of butyl acrylate (BA), methyl methacrylate (MMA), hexafluorobutyl methacrylate (HFMA) and hydroxy propyl methacrylate (HPMA), which was initiated with potassium persulfate (KPS) and emulsified with the novel mixed surfactants of sodium dodecyl benzene sulfonate (SDBS) and myristyl hydroxypropyl sulpho betaine (betaine). The structure of the latex was confirmed by Fourier transform infrared spectroscopy (FTIR). The particle size of the latex was measured by Zetatrac dynamic light scattering detector. The properties of latex film were tested by differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), contact angle (CA) and DSC. The stability of the latex was improved.
