Abstract

A process for the continuous preparation of aqueous plastic dispersions which comprises emulsifying one or more free-radically polymerizable monomers in an aqueous phase in the presence of an emulsifying agent, in an agitator vessel; initiating the free-radical polymerization of said monomer or monomers in said aqueous phase; and passing said aqueous emulsion of the free-radically polymerizing monomer or monomers through a tubular reactor whose internal surface comprises an (optionally fluorinated)saturated polyolefin.
