Synthesis and Properties of Hydrolyzed Silane Fluorinated Acrylate Ester Resin

In the synthesis of effects of synthetic fluorinated acrylate ester resin, monomer dropping time, reaction temperature and initiator content on the resin molecular weight, molecular weight distribution and the exothermic reaction were investigated, and the optimum synthesis conditions were determined. Functional groups and glass transition temperature were analyzed by infrared spectroscopy (FT-IR) and differential scanning calorimetry (DSC). Also, influences of acrylic silyl ester monomer content, the fluorine- containing acrylic acid monomer content and methylated on resin hydrolysis rate were observed. The results showed that the hydrolysis rate of the resin increased with the increase of the content of acrylic silyl ester monomer and decreased with the increase of the content of the fluorine monomer. When the silyl acrylate monomers used in the synthesis didn't contain methyl groups, the hydrolysis rate was relatively high.
