A method for producing a resin particle dispersion includes using a resin particle dispersion production apparatus including: two or more resin particle dispersion production lines each including an emulsification tank in which a resin is subjected to phase inversion emulsification using two or more organic solvents and an aqueous medium to thereby obtain a phase-inverted emulsion, a distillation tank in which the organic solvents are removed from the phase-inverted emulsion by reduced pressure distillation to thereby obtain a resin particle dispersion, and plural distillate collection tanks that collect distillates formed during the reduced pressure distillation according to respective target distillate compositions; and a reusable distillate storage tank A that collects and stores a distillate collected in at least one distillate collection tank A among the distillates collected in the plural distillate collection tanks in each of the two or more resin particle dispersion production lines. The distillate collected in the reusable distillate storage tank A is delivered to the emulsification tank in at least one resin particle dispersion production line among the two or more resin particle dispersion production lines to reuse the distillate for production of a phase-inverted emulsion in the at least one resin particle dispersion production line.

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.

A continuous process for producing a polyurea concentrate or powder. The process includes combing at least one amine and an isocayante in the presence of a liquid diluent or a base oil in a rotor stator mixer. The concentrate comprises a polyurea in a base oil wherein the concentration of from about 20 weight percent to about 50, or 40 or 35 or 30 weight percent of polyurea based on total weight of grease thickener. The powder has particle size of 2 to 400 microns. This concentrate or powder can then be formulated by grease manufacturers to the desired final properties without the need for handling of the isocyanate and amine raw materials.
