ABSTRACT:
Powders of polyolefin resins such as polyethylene homopolymer are obtained by agitating molten resin in admixture with water and in the presence of a dispersing amount of an alkali metal salt of an amino acid dispersant. The particle size distribution of the dispersed resin can, if desired, be regulated by the addition of base thereto.
