标 题 :Ziegler-natta catalyst for narrow to broad MWD of polyoefins, method of making, method of using, and polyolefins made therewith
发明人：GRAY STEVEN D; COFFY TIM J
权利人:FINA TECHNOLOGY
摘要:A new synthesis of a Ziegler-Natta catalyst uses a multi-step preparation that includes treating a magnesium dialkoxide compound with halogenating/titanating agents, and an organoaluminum preactivating agent. The catalyst may be used in the polymerization of olefins, particularly ethylene, to control the molecular weight distribution and the fluff morphology of the resulting polyolefins.

摘要:A process for preparing long-chain branched isotactic polypropylene (LCB-PP) is provided. The process includes copolymerizing propylene with an asymmetric diene of formula I using a heterogeneous iso-specific MgCl 2 -supported Ziegler-Natta catalyst. The copolymerization results in an isotactic polypropylene-styrene (PP-St) copolymer of formula II. The process includes pelletizing the PP-co-BSt copolymer in an extruder to produce the LCB-PP. n is an integer from 1 to 4, x is an integer between 500 and 10,000, and y is an integer between 1 and 10.

摘要:A process for the production of amorphous polyolefins is disclosed. The process entails contacting the olefin monomer, in an unreactive hydrocarbon solvent, with a catalyst in a recirculated, stirred reactor thereby producing amorphous polyolefin. The reactor is capable of recirculating contents that are very viscous.
