Classification: CPC C  B | IPC B  C

Claim 0:
1. A method of flow synthesis of polymer nanoparticles, comprising:
feeding a mixture comprising a radical initiator to a continuous flow reactor comprising a channel;
heating the mixture in a preheating section of the continuous flow reactor;
feeding monomer to the continuous flow reactor;
mixing the monomer with the mixture in a reaction section of the continuous flow reactor downstream of the preheating section;
polymerizing the monomer in presence of the radical initiator in the reaction section to form polymer nanoparticles, wherein polymerizing the monomer comprises emulsion polymerization; and
discharging the polymer nanoparticles from the continuous flow reactor, wherein discharging the polymer nanoparticles comprises discharging a slurry from the continuous flow reactor, the slurry comprising the polymer nanoparticles and water, and wherein the polymer nanoparticles comprise a polydispersity index (PDI) less than 0.1.
