Abstract

Procedure for obtaining expanded bodies from olefin polymerizates, mixing an olefinic polymerizate with a highly volatile expansion agent at temperatures above the glass transition point of the olefinic polymerizate and under a pressure with which an expansion of the mixing, and extruding the expandable mixture in a zone of reduced pressure, characterized in that a modified olefinic polymer is used that contains 10 to 90% by weight of grafted styrene, based on the modified polyolefin.
