PROCESSO PARA A PREPARACAO DE COPOLIMEROS DE ETILENO |
摘要 |
Ethylene/1,5-hexadiene copolymers and higher interpolymers having structural characteristics that provide improved physical properties and processability. The ethylene polymers of the invention have narrow molecular weight distribution and/or narrow composition distribution and/or a low cluster index. The 1,5-hexadiene comonomer is predominantly incorporated as a cyclic ring in the polyethylene backbone but may also form long chain branching and intermolecular coupling without crosslinking to a gel. |
