Preparation and Properties of Fluorinated Poly-Acrylate Emulsion with TPG as Co-Solvent

Abstract

Fluorinated acrylate emulsion was prepared in the presence of TPG as co-solvent, effects of TPG content to the polymerization stability and monomer conversion of the prepared emulsion was studied by the coagulation ratio and conversion rate, respectively. The hydrophobicity and oleophilicity of the polymer film was studied by water/oil contact angle. The chemical structure and morphology of the latexes was studied by FTIR and TEM observation, respectively. The results show that TPG has great impact on the stability of emulsion polymerization and morphology of the latex particles. The prepared fluorinate poly-acrylate emulsion has excellent water/oil repellency and thermal stability.
