Abstract
Method of obtaining short fibrils by abrupt expansion of a biphasic mixture containing molten polymer and solvent and which is at elevated pressure and temperature by ejection through a hole so as to vaporize the solvent instantaneously and solidify the polymer, characterized in that the fluid of the biphasic mixture is disturbed at the moment in which it enters the expansion orifice.
