ABSTRACT:
A stripping process is provided which continuously strips volatile substances from a dispersion containing a polymer particles through stripping the volatile substances from a dispersion by blowing an inert gas into the dispersion to draw the volatile substances into the inert gas, removing the volatile substances from the gas mixture of the inert gas and the stripped volatile substances and circulating the purified inert gas obtained by removing the volatile substances from the gas mixture, and blowing the purified inert gas into the dispersion. Also provided is a production process for a toner which uses this stripping process.
