- Abstract
Cross-linked vinyl acetate and vinyl versatate (VeoVa) polymer latex (VAc-VeoVa10) modified with fluorine and silicon was successfully synthesized via the semi-continuous seeded emulsion polymerization technology. The latex was emulsified by green surfactants of sodium alphaolefin sulfonate(α-AOS) and cashew phenol polyoxyethylene ethers(BCE-10) and initiated with potassium persulfate(KPS). The chemical structure of the latex was analyzed by fourier transformed infrared (FTIR). The glass transition temperature (Tg) was detected by differential scanning calorimetry(DSC) measurement. The water resistance was determined by the water contact angle (WCA) measurement. The polymerization condition of preparing the latex was optimized. Results showed that the content of surfactant was 2.00Wt% and the mass ratio of α-AOS and BCE-10 was 2:1 and the mass ratio of main monomer was 3:1.The contents of fluorine monomer and the silicon monomer were 8.00 wt% and 1.00wt%, respectively. The amount of the cross-linked monomer was 1.00wt%. In comparison with the conventional latex, the hydrophobic performance of the cross-linked modified VAc-VeoVa copolymer latex was improved.
