Abstract
The invention provides a continuous-flow process for producing a polymeric material. The process of the invention comprises the steps of: introducing at least two solutions, each comprising one or more reactants, into a microreactor to mix the two solutions to form a reacting solution, wherein the one or more reactants are selected from the group consisting of a monomer, an initiator, a coupling agent, a prepolymer, a macromer, and mixtures thereof; feeding continuously the reacting solution into a flow-through polymerization reactor in a coil form, wherein the flow-through polymerization reactor is capable of providing a residence time sufficient for (co)polymerizing the reactants to form a polymer with a desired polydispersity, wherein the flow-through polymerization reactor is immersed in an ultrasonic bath to minimize or substantially eliminate unwanted high-molecular-weight fractions of the polymer.
