Abstract
The invention concerns a process for controlling the stability or the droplets sized of simple water-in-oil emulsions, wherein a di-block or tri-block copolymer is used. A block is a hydrophilic block, the other block is a hydrophobic block. The invention concerns also a stabilized water-in-oil emulsion.
