Abstract
The novel acrylate emulsion was prepared by semi-continuous seeded emulsion polymerization of butyl acrylate (BA), methyl methacrylate (MMA), hexafluorobutyl methacrylate (HFMA, C8 H8 F6 O2 ) and benzyl methacrylate (BZMA, C11H12O2 ) which were emulsified with the mixed surfactants of b-Cyclodextrins (b-CD) and sodium dodecyl benzene sulfonate (SDBS) and initiated with potassium persulfate (KPS). Many factors such as the amount and mass ratio of emulsifier, and monomer, dosage of initiator, which have an influence on the polymerization stability, have been investigated in detail. The films of the resultant latex are characterized by FTIR, DSC and TGA. The novel emulsion has a good hydrophobicity and a low surface energy. Furthermore, the thermal stability of the modified emulsion is improved significantly.
