ABSTRACT:
A process for forming dispersions of olefin polymers and copolymers using an alkali metal soap of fatty acids as the dispersing agent.
Molten thermoplastic resins such as polyethylene are vigorously agitated in admixture with water and in the presence of a lithium salt of a higher fatty acid to produce a dispersion which is then cooled to a temperature below about 100.degree. C. to produce the resin in a pulverulent form.
