摘要：Blends of at least two polymers incorporating propylene-derived units andprocesses for producing such blends are provided. The first polymer of the blend is a lowcrystallinity polymer including propylene-derived units. The second polymer is a highcrystallinity polymer including propylene-derived units. The polymer blends exhibit thebeneficial performance characteristics of low crystallinity propylene polymers whileminimizing certain processing and handling problems associated with low crystallinitypropylene polymers. Low crystallinity propylene polymer pellets often exhibit atendency to agglomerate because of the softness of such particles. Agglomeration ofthe pellets creates problems in handling and processing the particles. The polymerblends disclosed reduce the tendency of polymer pellets to agglomerate whilemaintaining the desirable physical properties, such as elastomeric properties, exhibitedby low crystallinity propylene polymers. Various processes for producing the polymerblends are also provided.
