Synthesis of Fluorine-containing Acrylate Emulsion

In this articlce,a novel method of preparing trifluorethyl acrylate monomer with trifluoro ethanol and acryloyl chloride is presented through the esterification reaction under the catalysis of 4-dimethylamino pyridine(DMAP) as the catalyst and cuprous chloride as the inhibitor.Based on the experimental results,the main factors effecting on the reaction were discussed to define the best synthetic conditions as follows.The ratio between acryloyl chloride and trifluoro ethanol(on mol) was 1.2∶1;the dosage of DMAP and CuCl was both 1 %(on wt of acryloyl choloride),and finally the reaction temperature was 60 ℃ and the total reaction time was 6 hours.And at the same time the product was characterized by FT-IR.The stable trifluorethyl acrylate monomer was prepared by trifluoroethyl acrylate and inoctadecyl acrylate as raw materials.The choices of the initiator and the systems,as well as the influences of various polymerization conditions were investigated.
