“…In the past few decades, polyacrylate latex has been widely used as a cement additive due to its excellent weather resistance, environmental protection and toughness [1,2]. A great number of studies have shown that the addition of polyacrylate latex improved the structure of hardened mortar, the flowability of cement paste, the mechanical properties of cement mortar, penetration resistance, freezing and thawing resistance, etc [3][4][5][6].…”

“…The hydrophobicity of the surface can be directly reflected by the value of the contact angle of water on the film surface (Yu et al, 2014). Effect of amounts of HFMA monomer and VTES monomer on the contact angle of the film was presented in Figure 8.…”

Purpose Fluorine and silicon materials have received the keen attention of many researchers because of their water repellency and low surface free energy. The purpose this study was to prepare vinyl acetate (VAc)-vinyl ester of neodecanoic acid (VeoVa 10) copolymer latex modified with fluorine and silicone monomer, which is emulsified with the novel surfactants of disodium laureth sulfosuccinate (MES) and octylphenol polyoxyethylene ether (OP-10). Design/methodology/approach A series of modified latices containing fluorine-silicon have been prepared by semi-continuous seeded emulsion polymerisation of mixed monomers of VAc, VeoVa10, hexafluorobutylmethacrylate (HFMA) and vinyltriethoxysilane (VTES) and emulsified by novel surfactants of MES and OP-10. Findings The optimum conditions for preparing the modified latex is as follows: the amount of the surfactant was 4.0 Wt.% and the mass ratio of the anionic and nonionic surfactant was 3:1; the dosage of initiator was 0.4 Wt.% and the mass ratio of the main monomer was 3:1; and the amounts of VTES and HFMA were 2.0 and 6.0 Wt.%, respectively. In comparison with the conventional latex, the hydrophobicity of latex film was improved further. Originality/value The modified p (VAC-VeoVa) latex is prepared via semi-continuous seeded emulsion polymerisation, which is emulsified with the novel mixed surfactants of MES and OP-10. There are two main innovations. One is that the novel p (VAC-VeoVa) latex containing fluorine-silicon is prepared successfully. The other is that the emulsifier is composed of the novel mixed surfactants of MES and OP-10.

“…Polyacrylate latexes are efficient, environmentally friendly materials, which have attracted more attention because of the low volatile organic compounds and extensive applications in our daily life as adhesive, coatings, particularly as building coating [1][2][3] . To modify the age-resistance and physical properties of polyacrylates, many researchers have focused on synthesizing the fluorine-containing polyacrylates or fluorinated polyacrylate emulsion and core-shell latexes [4][5][6] . However the major shortcomings of polyacrylate material are low glass transition temperature (T g ) and relatively poor thermal stabilities.…”

Core-shell nanocomposites were prepared from acrylates, fluorine-containing methacrylate monomers and methylacryloypropyl polyhedral oligomeric silsesquioxanes (MAP-POSS) by emulsion polymerization. The properties of latex and nanocomposites were characterized by FTIR, NMR, TEM, laser particle diameter analyzer, DMA and TGA. The results showed that the particle diameter of composite latexes was about 33.5 nm, dynamic mechanical loss peak temperature T p of the nanocomposites had the best high value at 99.6°C when 7 wt.% MAP-POSS was added, which is 7.8°C higher than the pure polyacrylates. MAP-POSS could increase the thermal stability of materials, the initial thermal decomposition temperature increases about 34°C.
