Hybrid Latex

Fluorine-containing acrylate monomer modified acrylate hybrid latex particles were synthesized by seeded emulsion polymerization with methyl methacrylate (MMA), butyl acrylate (BA), methacrylic acid (MAA), hydroxyethyl methacrylate (HEMA), and trifluoroethyl methacrylate (TFMA) in the presence of three kinds of surfactant mixture conditions, respectively. The effect of different surfactant mixtures on properties of fluorinated acrylate latex and film were investigated. Chemical composition and morphology of the resultant hybrid latex particles were respectively characterized by Fourier transform infrared (FT-IR) spectroscopy and transmission electron microscopy (TEM). The addition of a small amount fluorine-containing surfactant leads to an increase of the monomer conversion and improvement of thermal stability of the latex. The average particle size of the latex prepared in the presence of OP-10/Le-180s/CO-436/Le-003 surfactant mixture was uniform and the particle distribution was narrow; thermogravimetric analysis (TGA) indicated the hybrid latex possessed good thermal stability, and the result also revealed the latex exhibited good dilution, refrigeration as well as Ca2+ stability.

AbstractVinyl polymer/polyurethane hybrid latex particles with various compositions were successfully prepared via emulsion polymerization of vinyl monomer in the presence of self-emulsified polyurethane dispersion without using any surfactant. Studies were carried out on polymerization kinetics, characterization of the hybrid particles and the physical properties of nano-sized vinyl polymer particle/thermoplastic polyurethane blends. It was found that the maximum content of vinyl polymer in polyurethane hybrid particles was up to 80 percent and all of the vinyl polymer/polyurethane hybrid particles were less than 120 nm. Infrared spectroscopy, thermal gravimetric analysis and differential scanning calorimetry analysis indicated the influence of vinyl polymer on the polyurethane hybrid particles. With the polyurethane shells outside and, therefore, good compatibility with polyurethane matrix, the hybrid particles can be easily blended into polyurethane matrix. Some unusual changes of dynamic mechanical properties in the low temperature region were found in the blends of hybrid particles and thermoplastic polyurethane. With the addition of only 3%, the mechanical properties of these blends did not show a significant change. This study provided a new method to prepare hybrid particles in the absence of surfactant and made an attempt on application of vinyl polymer/polyurethane hybrid particles in the blending modification
