Zusammenfassung:	There is disclosed a continuous method for agglomerating lactices of a polymer to provide large particles. An acid anhydride solution is continuously admixed with an aqueous latex of a polymer followed by passing the admixture through a conduit with laminar-flow wherein the passage-time through said conduit is sufficient to hydrolyze the acid anhydride and produce agglomeration of said particles providing an agglomerated admixture followed by continuously stabilizing said agglomerated admixture with an emulsifying material providing a stabilized agglomerated latex.
