Abstract:

A new fluoride-bearing polyacrylate emulsion was synthesized with the polyacrylate emulsion containing epoxy groups as the main material and m-(trifluoromethyl)aniline as the modifier.The synthesis conditions as well as the structure and properties of the product were also investigated.Th e results indicate that the water absorbability of fluoride-bearing polyacrylate emulsion decreases from 1 1.5% to 8.5% .the tensile elongation at break decreases from 610% to 300% ,while the contact angle，the tensile strength and the modulus at 100% elongation respectively increase from 73°to 78°.3 MPa to 8 MPa and 0.57 MPa to 2.87 MPa.

Key words: polyacrylate emulsion, fluoride-bearing polyacrylate emulsion, m-(trifluoromethyl)aniline, glycidyl methacrylate, synthesis
