Polypropylene preparation |
摘要 |
A propylene polymerization process is disclosed. The process gives polypropylene having isotactic and atactic stereoblock sequences. The process is performed in the presence of a non-bridged bisindenoindol-based single-site catalyst. The polypropylene produced has an isotactic pentad (mmmm) content within the range of about 10 mole % to about 70 mole %.
