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： Low molecular weight semicrystalline propylene-alpha olefin copolymers containing propylene crystallinity are used as a nucleating agent in crystalline polypropylene and polypropylene copolymers. The nucleating copolymers are propylene-alpha olefin copolymers having a percent crystallinity of 5-75%, a melting point of 45° C.-105° C., and an MFR between 300 and 5000 g/10 min. Nucleated polypropylene compositions comprise a nucleating amount of the copolymer blended in a matrix of polypropylene homopolymer, or 0.01 to 9 wt % α-olefin copolymer, having a melting point greater than 110° C. The nucleating copolymer improves processing time with little or no effect on the crystallinity-associated characteristics of the matrix. The invention also provides methods of crystallizing polypropylene with the nucleating agent and of forming articles with the composition, and also provides articles formed from the composition and/or by the method.
