INVESTIGATION OF PPA INTERACTIONS WITH POLYMER MELTS INCOEXTRUSION FLOWS

摘要

Recently proposed new slip model based on 'effective continuum methods' was developed and used for investigation of process aids interactions with polymer melts in single as well as multi-layer flows. Specific attention has been paid to understanding the role of process aids on stabilization of the zig-zag type of interfacial instabilities in film blowing coextrusion.
