Paper Title:
Copolymerization of Organosilicone-Veova10-VAc Emulsion Modified with Protective Colloid of PAM-PEG
  Abstract

The purpose of this work is to modify the organosilicone-veova10-vinyl acetate (OSVVVA) copolymer emulsion with protective colloid in order to improve the viscosity of the original emulsion. The protective colloid was first prepared with polyacrylamide and polyethylene glycol as raw materials. The effects of use levels of protective colloid, vinyl triethoxyl silicane and potassium persulfate and reaction temperature on emulsion properties were investigated by orthogonal experiment and their optimum values were determined to be:50 g, 4 g, 0.5 g and 84 °C, respectively, under which the viscosity of the modified OSVVVA emulsion was greatly increased from 120 mPa•s to 430 mPa•s and the other properties of the modified OSVVVA were also satisfactory. The infrared spectra of the modified OSVVVA emulsion proved that the protective colloid was successfully grafted onto the OSVVVA copolymer emulsion.
