CATALYST COMPOSITIONS COMPRISING SUPPORT MATERIALS HAVING AN IMPROVED PARTICLE-SIZE DISTRIBUTION |
摘要 |
A catalyst composition that includes a support material having an improved particle-size distribution is provided. Processes for producing polyolefin composition also are provided. Polymers and films also are provided. An example of a catalyst composition is a supported multi-transition-metal catalyst composition that includes: (a) at least two catalyst components selected from the group consisting of: a nonmetallocene catalyst component and a metallocene catalyst component; (b) a support material that has a D50 of less than about 30 microns and a particle size distribution having a D90/D10 ratio of less than about 6; and (c) an activator.
