| 1. A free radical polymerization process, comprising:
reacting at least one free radically polymerizable monomer with at least one initiator in the present of at least one ionic
liquid undergoing polymerization to obtain a polymer with a PDI of 1.5 or less,
wherein the free radically polymerizable monomer is nitrogen-containing monomer, and the ionic liquid has a formula (IV),
of:
 wherein
Y− is SbF6−, PF6−, BF4−, (CF3SO2)2N−, CF3SO3−, CH3CO2−, CF3CO2−, NO3−, Cl−, Br−, or I−; and
R1, R2, R3 and R4 are each independently C1-10 fluoroalkyl group, or C1-10 perfluoroalkyl group.
