Abstract

A process for stabilising olefin polymers having a mean particle diameter of from 1 to 5 mm that have been polymerised on carrier catalysts, which comprises treating the polyolefins with a stabiliser mixture prepared by heating to from 120 to 260°C a mixture containing a) at least one carrier and/or b) at least one stabiliser that melts at from 20 to 120°C and c) at least one stabiliser that melts at from 120 to 260°C, and then cooling said mixture until solidified, components b) and c) being different.
