The current invention concerns a method for preparing an emulsion comprising the steps: mixing a first phase and a second phase in a layer multiplier to produce a multilayered fluid structure, and collapsing said multilayered fluid structure, thereby dispersing the second phase in the first phase creating an emulsion. The current invention relates to a method for producing dispersions. The current invention also concerns the emulsions produced by said method. The current method also relates to polymer emulsions, particularly polyisobutene emulsions with a high content of polyisobutene.

C08J 3/09 - Making solutions, dispersions, lattices or gels by other methods than by solution, emulsion or suspension polymerisation techniques in organic liquids
The invention relates to a method for preparing a stable and thin liquid polyisobutene emulsion comprising the steps of i) heating a polyisobutene polymer, optionally mixing said polyisobutene polymer with a wax and/or oil, thereby obtaining a pre-mix, ii) mixing said pre-mix in water containing one or more surfactants in a concentration of the surfactant of maximum 5% wt. at a controlled flow rate, which flow rate is sufficiently slow to form particles of the pre-mix, thereby obtaining a pre-emulsion, and iii) homogenizing said pre-emulsion, thereby obtaining said polyisobutene emulsion with an average particle size of at maximum 100 μm.
