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.
摘要翻译： 提供了至少两种结合丙烯衍生单元的聚合物的混合物和用于生产这种共混物的方法。 共混物的第一种聚合物是包含丙烯衍生单元的低结晶度聚合物。 第二聚合物是包含丙烯衍生单元的高结晶度聚合物。 聚合物共混物表现出低结晶度丙烯聚合物的有利性能特征，同时使与低结晶度丙烯聚合物相关的某些加工和处理问题最小化。 由于这种颗粒的柔软性，低结晶度丙烯聚合物颗粒通常表现出聚集的倾向。 颗粒的聚集在处理和加工颗粒中产生问题。 所公开的聚合物共混物降低了聚合物颗粒聚集的趋势，同时保持了低结晶度丙烯聚合物所表现的所需的物理性能，例如弹性体性质。 还提供了用于生产聚合物共混物的各种方法。
