Abstract
A method of producing small spherical polymer particles from systems containing two liquid phases, the one phase of which contains one or more dissolved substances and is dispersed in the form of small droplets in the other phase to form an emulsion, whereafter the droplets are converted to a solid form. The liquid phases used are two mutually immiscible aqueous phases.

A method of producing small spherical polymer particles from a system containing two mutually immiscible aqueous liquid phases, the one phase of which contains one or more dissolved polymer substances and is dispersed in the form of small droplets in the other phase to form an emulsion, whereafter the droplets are caused to solidify to form said particles, and wherein said two mutually immiscible aqueous liquid phases both contain dissolved substances which will cause the formation of dispersed droplets when the two phases are brought together.
