Title:
反応体ブレンドのポリプロピレン、その製造法及びメタロセンリガンドの製造法
Document Type and Number:
Japanese Patent JP3824325
Kind Code:
B2
Abstract:
Fractionable, reactor blend polypropylenes, directly obtainable from the polymerization reaction of propylene, having: (a) content of isotactic pentads (mmmm) comprised between 25 and 85%; (b) ratio Mw/Mn<5; containing from 10 to 70% by weight of a fraction soluble in boiling diethyl ether, said fraction having a content of isotactic pentads (mmmm) comprised between 5 and 25%, and from 30 to 90% by weight of a boiling n-heptane-insoluble fraction, soluble in xylene at 135 DEG C., said fraction having a content of isotactic pentads (mmmm) comprised between 50 and 99%, are disclosed. These polymers are suitable as thermoplastic-elastomeric materials. A process for the preparation of these polymers and a process for the preparation of 2-aryl-substituted indenyl metallocene ligands is also disclosed.
