| titleOfInvention | Solution polymerization process for the preparation of high-density polyethylene with long-chain branching |
| abstract | The polymerization method comprises contacting an ethylene feed comprising ethylene monomer with a catalyst feed comprising a hafnium-based or zirconium-based single-site catalyst in solution, thereby polymerizing the ethylene monomer to have an average of less than 10 and greater than 0.25 long chain branches /Long-chain branched high-density polyethylene of polymer chains. A polymeric composition comprising ethylene; a hafnium-based or zirconium-based single-site catalyst; and a long-chain branched high-density polyethylene polymer product, wherein the long-chain branched high-density polyethylene has an average of less than 10 and greater than 0.25 long-chain branches per polymer chain; and wherein at least one of ethylene, catalyst and product is in solution. |
