Organic chemical foaming agent monomers, MATSH(metacryloyl toluenesulfonyl hydrazide), MAOBSH(metacryloyl oxybisbenzenesulfonyl hydrazide) were first synthesized from TSH/OBSH with MAC(methacryloyl chloride), then polymerized by conventional free radical techniques. TSH, OBSH, and their monomer and polymer nanoparticles were fabricated by O/W(oil in water) emulsion method in PVA(poly vinyl alcohol) aqueous solution. Organic chemical foaming agent monomers, polymers and their nanoparticles were characterized by dynamic light scattering(DLS), transmission electron microscopy(TEM) image, scanning electron microscopy(SEM) image, fourier transform infrared spectroscopy(FT-IR), 1H nuclear magnetic resonance spectroscopy(1H NMR), thermogravimetric analysis(TGA) and differential scanning calorimetry(DSC). |
