摘要： Temperature resistant multilayer composites, methods for making same, and articles made therefrom. The method can include extruding one or more polyolefm polymers having a MFR from less than 90 dg/min through at least one die having a plurality of nozzles to form a plurality of continuous fibers, at least one die operating at a melt pressure from greater than 500 psi (3447 kPa) to form at least one elastic meltblown layer; adhering the at least one elastic meltblown layer to at least one extensible layer to form a multilayer composite; and at least partially crosslinking the elastic meltblown layer or the extensible layer or both.

摘要： Blends of at least two polymers incorporating propylene-derived units and processes for producing such blends are provided. The first polymer of the blend is a low crystallinity polymer including propylene-derived units. The second polymer is a high crystallinity polymer including propylene-derived units. The polymer blends exhibit the beneficial performance characteristics of low crystallinity propylene polymers while minimizing certain processing and handling problems associated with low crystallinity propylene polymers. Low crystallinity propylene polymer pellets often exhibit a tendency to agglomerate because of the softness of such particles. Agglomeration of the pellets creates problems in handling and processing the particles. The polymer blends disclosed reduce the tendency of polymer pellets to agglomerate while maintaining the desirable physical properties, such as elastomeric properties, exhibited by low crystallinity propylene polymers. Various processes for producing the polymer blends are also provided.
