Claim 18:
19. A method of flow synthesis of polymer nanoparticles, comprising:
flowing a first mixture comprising a radical initiator and water to a continuous flow reactor having a flow channel for reactant flow;
flowing monomer to the continuous flow reactor;
forming in the continuous flow reactor a second mixture comprising the first mixture and the monomer;
polymerizing, via emulsion polymerization, the monomer in the second mixture in the continuous flow reactor to form polymer nanoparticles; and
discharging a slurry from the continuous flow reactor, the slurry comprising the polymer nanoparticles, water, and residual monomer, wherein the polymer nanoparticles comprise polymer from acrylamide or acrylic acid, wherein the polymer nanoparticles comprise a polydispersity index (PDI) less than 0.1.
