摘要： 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.

摘要： The invention relates to an aqueous polyisobutene emulsion comprising : 1 %wt. to 65 %wt., based on the total weight of said emulsion, of polyisobutene, - at maximum 5 %wt., based on the total weight of said emulsion, of at least one surfactant, and - optionally 1 %wt. to 65 %wt., based on the total weight of said emulsion, of at least one wax and/or oil, complemented with water to 100 %wt., whereby the average particle size of said polyisobutene emulsion is not greater than 100 μm. The present invention also relates to the use of such an emulsion.

摘要： The current invention concerns a method for preparing a polyisobutene (PiB) in water emulsion characterized by the steps :
- combining a number of separate fluid streams of PiB and water with formation of alternating fluid lamellae of PiB and water,
- focusing the alternating fluid lamellae of PiB and water with formation of a focused total fluid stream,
- gradually tapering the cross-flow section of said focused total fluid stream in the direction of the flow in a manner that decays said alternating polyisobutene and water fluid lamellae.
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.
The current method also relates to a method for reducing the average droplet diameter of an emulsion, comprising the steps :
- providing an emulsion, comprising droplets of a dispersed phase within a continuous phase, characterized by an average droplet diameter and a viscosity ratio of the dispersed phase to said continuous phase of at least 4.0, and
- reducing said average droplet diameter by forcing said emulsion through a gradually tapered cross-flow section of in the direction of the flow in a manner that decays said alternating polyisobutene and water fluid lamellae.-
