FIELD: chemistry.
SUBSTANCE: method includes at least a stage of the ethylene polymerization in the presence of a metal complex selected from the following structural formulae I
,
where M is metal of group 4 of the Periodic Table of the Elements, R1a, R1aa, R2a, R2aa, R3a, R3aa, and R4a, R4aa, R5a, R5aa, R6a, R6aa, and R7a, R7aa, R8a, R8aa, R9a, R9aa, R11a, R11aa, R12a, R12aa, R14a, R14aa, R15a, R15aa independently in each case represent a hydrogen atom, a halogen atom, hydrocarbon, each of R10a, R10aa, R13aa, and R13a independently represents (C1-C40) hydrocarbyl, X independently represents (C1-C20) hydrocarbyl, Z represents O, Y represents hydrocarbyl, L represents (C1-C40) hydrocarbilen. A polymer based on ethylene, a composition, an article, and a metal complex are also provided.
EFFECT: invention makes it possible to obtain high molecular weight polymers at lower viscosities in the reactor.
