A process of extruding a blend of an irradiated first propylene polymer and a non-irradiated second propylene polymer, where the first propylene polymer comprises a non-phenolic stabilizer. The irradiation of the first propylene polymer extrudate is conducted in a reduced oxygen environment, and the irradiated first propylene polymer and the non-irradiated second propylene polymer are blended at a temperature below their respective melting points. The blend has a viscosity retention of 20 to 35%.

Controlled rheology formulations containing high melt strength polypropylene for extrusion coating

The present invention relates to a process comprising extruding a blend of an first propylene polymer comprising a non-phenolic stabilizer and a non-irradiated second propylene polymer, wherein the irradiation of the first propylene polymer was conducted in a reduced oxygen environment, and the irradiated first propylene polymer and the non-irradiated second propylene polymer were blended at a temperature below the melting point of the first and second propylene polymers.

Extrusion processes using high melt strength polypropylene

A process of extruding a blend of an irradiated extrudate of a first propylene polymer and a non-irradiated second propylene polymer, where the first propylene polymer comprises a non-phenolic stabilizer. The irradiation of the first propylene polymer extrudate is conducted in a reduced oxygen environment, and the irradiated extrudate of the first propylene polymer and the non-irradiated second propylene polymer are blended at a temperature below their respective melting points. The blend has an ARPSW of &#x2266;3.0 micron.
