CO-CONTINUOUS HETEROPHASE POLYMER COMPOSITIONS CONTAINING HIGH MELT STRENGTH POLYPROPYLENE FOR EXTRUSION COATING |
摘要 |
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 ≦̸3.0 micron. |
