Abstract:
A method of coupling a diazonium salt with an organic polymer comprising, in the following order, the steps of:a) dissolving an organic polymer having a weight average molecular weight ranging from about 500 to 2,000,000 in a solvent, thereby providing one liquid phase; b) providing a diazonium salt in another solvent, thereby providing a separate liquid phase; c) contacting the diazonium salt liquid phase and the organic polymer liquid phase, for a period of time that is greater than or equal to the minimum reaction time required to react said diazonium salt with said organic polymer, and thereby reacting said organic polymer and said diazonium salt; further comprising intimately mixing the separate phases using an in-line mixing unit selected from: a static tubular reactor and a dynamic mixer.
