Abstract
Hexafluorobutyl methacrylate (HFMA) was predissolved as sole co-stabilizers in miniemulsions in order to improve the surface properties of films prepared by final latex, and a semibatch polymerization was used for enhancing the HFMA usage efficiency. In miniemulsion polymerization, the effects of the HFMA on the stability of monomer droplet were investigated. The ratio of the final latex particles number to the initial monomer droplets number was used to discuss the nucleation formation process. In a semibatch minimeulsion reaction, the effect of HFMA dropping policy on the size of final latex particles was discussed and morphology of the latex particles observed. Although the HFMA consumption was equal in all semibatch experiments, the surface properties of film prepared by final latex demonstrated a strong difference.
