Abstract

The present application is directed to methods for preparation of polymer particles in gel form and carbon materials made therefrom. The carbon materials comprise enhanced electrochemical properties and find utility in any number of electrical devices, for example, as electrode material in ultracapacitors or batteries. The methods herein can also be employed generally to improve emulsion and/or suspension polymerization processes by improved control of diffusion of acidic and basic species between the polymer and secondary phases.
