Preparation and Characterization of Fluoroalkyl Methacrylate Copolymer Emulsion Using in Glass Fiber

Yi Ming Sun, Xie Xia, Xu Huang Chen, Yan Lin Chen

Abstract

Copolymer emulsions containing fluorine were prepared by emulsion polymerization with MMA, BA and G06B using SDBS as emulsifier. The copolymer was characterized by FTIR and DSC. The size and distribution of the latex particle in emulsion were obtained by particle size analyzer. The stability of emulsion was observed and the solvent resistance of latex films was investigated. Surface properties of the copolymer film were investigated by contact angle measurement. The results showed that adding fluorine group to copolymer could increase hydrophobic property of the latex film and decrease the surface free energy of copolymer film. Glass fiber will have excellent properties when combining with the copolymer emulsion.
