pH value and partition of composite emulsifier between nucleus and shell on the stability of acrylate emulsion was studied. The result showed that using hindering organic siloxane monomer with isopropoxy
adjusting the pH value in the range of 4.5—7
adding the right amount of hydrolyzation inhibitor
and taking post addition of organic siloxane can decrease the degree of hydrolyzation and fasculation
improve polymerization stability and increase the graft ratio and content of organic siloxane
and hence obtain an emulsion with good performance.
