摘要：

The effect of radical polymerization inhibitors on the aggregative stability of latexes of styrene copolymers with acrylonitrile and ethoxyethyl acrylate, prepared with Sintanol ALM-10 nonionic emulsifier, was studied. Stable free macroradicals can be one of the factors responsible for the loss of the aggregative stability of the latexes. The mechanism of the action of macroradicals on the adsorption layer of polymer-monomer particles was suggested, and the stabilizing power of naphthalene-containing dispersants was accounted for on the basis of this mechanism.
