EXTRUSION COMPOSITIONS WITH IMPROVED MELT FLOW

摘要

Extrusion compositions having improved melt stability and suitable for use in high-speed extrusion coating operations are disclosed. The compositions are a dynamically modified mixture of a first polymeric component which is a reactor-made or physically blended mixture of polypropylene and an ethylene-propylene copolymer, a second polymeric component which is a fractional melt index homopolymer or copolymer of ethylene and an organic peroxide.
