초록

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.

청구항

1. A method for stabilizing a simple water-in-oil emulsion comprising droplets of an aqueous phase dispersed in a hydrophobic phase, said method comprising the step of forming an emulsion comprising:a block copolymer comprising: (block A)-(block B) linear di-block copolymers,(block A)-(block B)-(block A) linear tri-block copolymers, or(block B)-(block A)-(block B) linear tri-block copolymers, anda surfactant that is different from the block copolymer;wherein:block A is a hydrophilic block, and comprises: vinyl alcohol;vinyl pyrrolidone;acrylamide;methacr...
