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. |
