ABSTRACT

The topology of formation of polymer-monomer particles, polymerization of vinyl acetate (VA) and styrene in a heterogeneous static monomer-water system, in the presence of hydroquinone and azobisisobutyronitrile (AIBN) has been studied by photo and spectrophotometric observation methods. It was established that in a static heterogeneous monomer-water system, regardless of the nature of the monomer and initiator, the dispersion of the monomer and the generation of latex particles in the form of microdroplets of the monomer occur at the interface. It is suggested that the stability of the resulting colloidal system is due to the terminal hydrophilic groups of the polymer and oligomeric molecules formed as a result of radical reactions taking place in the aqueous phase. The concluded assumption is that the stability of the obtained colloidal system is due to the polymer and oligomer end hydrophilic groups of in the aqueous phase.
