Use of hydrophilic organomodified siloxanes as a processing aid for melt granulation

摘要

Disclosed is the use of an organomodified polysiloxane of formula (I) as a release agent in melt granulation. The polysiloxane of formula (I) is a polyether polysiloxane, having repeating alkoxy units of ethoxyl followed by propoxyl and optionally additionally butoxyl or styrene units to comprise the grafted chains at R1, R2 and R3 positions.
