Abstract
A process for preparing fine powder particles of thermoplastic elastomer polymer is disclosed. This process comprises suspending thermoplastic elastomer solids in a poor solvent for the polymer using mild agitation and then admixing this suspension with a non-solvent for the polymer in the presence of high shear mixing. Powder particles having an average diameter of less than about 100 microns are obtained.
