Method of manufacturing a long-chain branched polymer and long chain branched polymer

摘要

(57) to provide a process for producing polymers and SUMMARY novel, a polymer incorporating a linear long chain side chain branching. Has a molecular weight greater than the critical molecular weight for entanglement of the polymer, and a branch of at least some long-chain linear branching occurs at a frequency of branches 1000 carbon atoms per 5.0 less than the polymer backbone. The linear long-chain branched polymers can be prepared by incorporating metallocene catalyzed polymerization α- olefin polymer cross-linked in the slurry method and solution. Processing and excellent properties of the polymer melt, the polymer is characterized by excellent mechanical properties of solid polymer. The polymer is useful by a secondary conventional processing techniques, for secondary processing in a wide range of products.
