A process peroxidically treats olefin polymers with di-tert-butyl peroxide in an extruder. The olefin polymers together with di-tert-butyl peroxide under an inert gas are fed to an extruder. The olefin polymers are used in a finely divided form at from 55 to 110° C. The use of peroxidically treated olefin polymers for producing moldings, fibers, films or nonwoven spunbond fabrics is described, as is a process for producing moldings, fibers, films or nonwoven spunbond fabrics.
