1. A process of making a monomer; said process comprising processing, in a microfluidic reactor the following materials:
a) a multifunctional phenol;
b) at least one cyanogen halide; and
c) a base selected from the group consisting of an organic base, an inorganic base and mixtures thereof;
at a temperature of from about −78° C. to about 25° C., said materials having residence time of from about 0.1 seconds to about 600 seconds.
