Soap Free Emulsion Polymerization

Nano-TiO2Modified Fluorine-Containing Polyacrylate Soap-Free Emulsion was Successfully Synthesized via Soap-Free Emulsion Polymerization Technique, in which the Polymerization Monomers Consisted of Methyl Methacrylate (MMA), Butyl Acrylate (BA) and Dodecafluoroheptyl Methacrylate (DFMA). the Influence of Amount of Initiator, Emulsifier, Containing Fluorine Monomer and nano-TiO2on the Performance of Emulsion was Investigated. the Results Showed that the Good Polymerization Stability, and High Monomer Conversion were Obtained when the Amount of Ammonium Initiator was 1.2%, the Amount of Reactive Emulsifier was 3.5%. with Increasing Amount of DFMA, the Monomer Conversion Decreased and the Gel Rate Increased Gradually with the Increase of DFMA Amount. UV-Blocking Ability of the Cotton Fabric Treated with the Hybrid Emulsion Containing Nano-Tio2increased with Increasing Amount of Nano-TiO2. IR Spectrum Results Showed that Nano-TiO2and Fluorine-Containing Monomer were Successfully Introduced in the Segmental Structure of the Polymer. SEM Revealed that Nano-TiO2was Loaded on the Surface of the Treated Cotton Fabric which had Good Hydrophobicity.
