| titleOfInvention | A kind of long-chain branched polyolefins and preparation method thereof |
| abstract | The invention provides a kind of long-chain branched polyolefins and preparation method thereof, including：Under the conditions of existing for titanium system Ziegler Natta catalyst, co-catalyst alkyl aluminum compound and branching agent, alkene is subjected to polymerisation, obtains long-chain branched polyolefins；The branching agent is that end group is unsaturated chain alkyl aluminium.Compared with prior art, the present invention uses titanium system Ziegler Natta catalyst of the phosphate compound for internal electron donor, using unsaturated chain alkyl aluminium as branching agent, so as to make obtained long-chain branched polyolefins have branch lengths with it is branched count out it is adjustable, the advantages of branched chain molecule amount narrowly distributing, simultaneously, unsaturated chain alkyl aluminium has preferable compatibility with main chain polyolefin, and contain a number of double bond in side chain, so that long-chain branched polyolefins can carry out in process it is appropriately crosslinked, it can further improve the melt strength and polymer impact performance of long-chain branched polyolefins. |
