Abstract

Procedure for the manufacture of discontinuous fibrils by abrupt expansion of a liquid biphasic mixture of molten polymer and solvent that are at high temperature and pressure so that instantaneous vaporization of the solvent is caused and said polymer is solidified, characterized in that introduces an addition fluid into said liquid biphasic mixture before the expansion is complete.
