MODIFIED POLYPROPYLENE COMPOSITIONS FOR REDUCED NECKING IN EXTRUSION FILM CASTING OR EXTRUSION COATING PROCESSES

摘要

The present invention discloses modified polypropylene composition with higher flow activation energy and reduced necking in extrusion film/coat, wherein composition comprises long chain branch of polypropylene; free radical initiator; primary antioxidant; secondary antioxidant; acid neutralizer; optionally multifunctional monomer. Further the said composition of polypropylene shows higher sensitivity of viscosity to temperature, with improved stretchability.
