Synthesis and characterization of novel acrylate emulsion containing phosphorus and silicon prepared via semi-continuous seeded emulsion polymerization

摘要

The novel acrylate emulsion containing phosphorus and silicon was prepared successfully via semi-continuous seeded emulsion polymerization. The conditions of synthesizing the novel emulsion were optimized. The films of the resultant emulsion were characterized by Fourier transform infrared spectroscopy (FTIR), differential scanning calorimetry (DSC) and contact angle (CA) determinator, respectively. Results show that the optimal condition synthesizing the novel emulsion was that the amount of PAM-200 is 2.00?g and the suitable way of adding KH-570 was to add KH-570 into the reaction after all other monomers were added and the optimal amount was 3.00%. Both FTIR and DSC confirm that the novel emulsion has been prepared successfully. CA indicates that the water resistance of emulsion film is improved clearly.
