Abstract
Procedure for the preparation of fibrils or microfibrils of synthetic polymers for paper, in which solutions, emulsions or dispersions of fibrogenic thermoplastic polymers in a liquid medium are extruded through a nozzle under conditions such that instantaneous vaporization of the liquid medium in the extrusion environment and are subjected to the impact, in said extrusion environment, of a gaseous fluid jet at high speed, with an angular direction with respect to the extrusion direction of said solution, emulsion or dispersion, characterized in that in its implementation The said fluid initially expands through a convergent-divergent type nozzle and by which the solution, emulsion or polymer dispersion is extruded in the divergent portion of said convergent-divergent nozzle.
