Abstract
A continuous fibrillated structure, formed by the abrupt pressure release of a two-phase liquid mixture of polymer and solvent at elevated temperature and pressure so as to cause the instantaneous vaporization of the solvent, is shredded by introducing a make-up fluid into the two-phase liquid mixture before the pressure release is complete.
