Abstract 1. A PROCESS OF PREPARING FIBERS OF POLYOLEFINS COMPRISING POLYMERIZING AN OLEFIN IN THE PRESENCE OF A COORDINATION CATALYST SYSTEM IN A REACTION MEDIUM WHOSE SOLUBILITY PARAMETER IS SUCH THAT ($S-$P)2 IS LESS THAN ABOUT 3.0 CAL./CC. AND AT A TEMPERATURE LESS THAN THE MELT DISSOLUTION TEMPERATURE OF THE POLYOLEFIN TO BE FORMED, AND SUBJECTING SAID POLYMERIZATION SOLUTION TO A POSITIVE SHEAR STRESS OF GREATER THAN ABOUT ZERO POUND (FORCE)/ SQUARE FOOT UP TO ABOUT 0.1 POUND (FORCE)/SQUARE FOOT DURING POLYMERIZATION, THE MAGNITUDE OF SAID SHEAR STRESS BEING SUFFICIENTLY GREAT TO PRECIPITATE THE POLYOLEFIN AS A FIBROUS GEL HAVING A FIBRILLAR STRUCTURE OF FIBROUS POLYOLEFIN IN WHICH THE INTERCONNECTING CAPILLARY SPACES ARE FILLED WITH REACTION MEDIUM, SAID MAGNITUDE SHEAR STRESS BEING LESS THAN THAT AMOUNT WHICH WOULD CAUSE THE DIRECT FORMATION OF A SUBSTANTIAL AMOUNT OF DISCRETE FIBERS DIRECTLY RECOVERABLE WITHOUT REQUIRING FURTHER PROCESSING STEPS, AND SUBSEQUENTLY SUBJECTING SAID FIBROUS GEL FORMED DURING POLYMERIZATION TO A SHEAR STRESS OF GREATER THAN ABOUT 0.1 POUND (FORCE)/SQUARE FOOT, THEREBY PRODUCING DISCRETE, DIRECTLY RECOVERABLE, POLYOLEFIN FIBERS WITHOUT REQUIRING FURTHER PROCESSING STEPS.
