Synthesis of Self-Stratifying Polyacrylate Latex Containing Silicon

Abstract:

Self-stratifying polyacrylate latex containing silicon was synthesized via semi-continuous emulsion polymerization, using organic silicon and acrylate as raw materials. Transmission electron microscope(TEM) characterization indicated that the particles were form uniform analogous core-shell structure and dynamic light scattering(DLS) analysis possessed narrow size distributions. The results of X-ray photoelectron spectroscopy(XPS) proved the propensity of silicon enrichment at film-air interface, which revealed self-stratifying phenomenon. The thermal stability of the latex films determined by thermogravimetric analysis(TGA) was increased 24 °C as the join of organic silicon.
