Title:
PREPARATION OF LONG-CHAIN BRANCHED ISOTACTIC POLYPROPYLENE
Document Type and Number:
WIPO Patent Application WO/2010/066906
Kind Code:
A3
Abstract:
The present invention discloses a method for preparing long-chain-branched isotactic polypropylene by first oligomerising propylene with a suitable oligomerisation catalyst system and then copolymerising propylene and the oligomer obtained in situ with a mono-aryl-substituted methylene bridged catalyst system.
