Abstract

Use of organomodified polysiloxanes which have at least three different polyether radicals, at least two of these polyether radicals differing by at least 9% by mass in the proportion of ethylene oxide units therein in the total weight of the polyether radical, as a release agent or release agent constituent in melt granulation.
