A new polymeric surfactant using for acrylicacid waterborne coatings was prepared from the methylacrylicacid, styrene, hydroxyethyl acrylate and 2-ethylhexyl acrylate.
The distribution of carboxylic group were determined by conductance titration and affected by the concentration of surfactant, the volume fraction and the amount of methylacrylicacid.
同时，用电导滴定法测定了乳胶粒表面羧基的含量，探讨了乳化剂浓度、羧酸含量及内相比对羧基分布的影响。

It was shown that the addition of functional monomer methylacrylicacid could not only improve emulsion stability but also be advantageous to formation of regular core shell structure.
