A process of making a solvent-free water-based emulsion of an anionically polymerized polymer which comprises: heating the polymer until its viscosity is no more than 3,000 centipoise, (b) mixing water with a surfactant, (c) adding the mixture of (b) to the polymer of (a) while agitating the polymer at high speed, thereby forming an emulsion, (d) cooling the emulsion to below 100° C., and (e) optionally subjecting the emulsion to turbulent flow and/or cavitation. Also included are emulsions of such polymers. |
