Abstract
A flow reactor system and methods having tubing useful as polymerization chamber. The flow reactor has at least one inlet and at least one mixing chamber, and an outlet. The method includes providing two phases, an aqueous phase and a non-aqueous phase and forming an emulsion for introduction into the flow reactor.
Claims20
A method comprising
- introducing an emulsion of a monomer and an acid into a flow reactor, the flow reactor comprising a length of tubing of inner diameter between about 1 to about 1000 micrometers;
- polymerizing the monomer;
- and
- forming a salt of the polymerized monomer with the acid within the length of tubing.

A method comprising
- introducing an emulsion of an aniline and an organic sulfonic acid;
- introducing the emulsion into a flow reactor, the flow reactor comprising a length of tubing of inner diameter between about one to about 1000 micrometers;
- introducing an oxidant to the emulsion or the flow reactor;
- and
- polymerizing the aniline in the inner diameter of the length of tubing and forming an acid salt thereof.
2 more elements
A polymerization apparatus for reacting one or more monomers producing one or more polymers, the polymerization apparatus comprising:
- an amount of tubing of inner diameter between about 1 to about 1000 micrometers, the tubing including at least one inlet and at least one outlet, the amount of tubing having at least one inlet port for receiving a reactant composition and at least one outlet port;
- a temperature controller sized to receive at least a portion of the tubing;
- a mixing chamber, the mixing chamber having an outlet fluidically coupled to the inlet of the tubing, and an inlet;
- at least one pressure unit operatively coupled to one or both of the inlet port or the outlet port of the amount of tubing, the at least one pressure unit configured to monitor, during polymerization of the one or more monomers, pressure in the amount of tubing or the difference in pressure between the inlet port and the outlet port of the amount of tubing;
- and
- at least one fluid flow control device fluidically coupled to the inlet of the mixing chamber.
