ABSTRACT:
Process for recycling inert particulate materials used in sticky polymer polymerization reactors by discharging the sticky polymer having unbound inert material on its surface into a product hold tank maintained at a lower pressure than the polymerization reactor and thereafter contacting said polymer with a sweep gas and at a velocity sufficient to remove the inert particulate material which is then recycled to the polymerization reactor.
