Claims (1)

Способ получения ЛПЭНП с повышенной способностью к переработке путем газофазной полимеризации, выполняемой в двух или более реакторах, при которой (порядок любой) в одном из реакторов полимеризуют смесь этилена и альфа-олефина CH2=CHR, где R-алкил, имеющий 1-10 атомов углерода, полученный в результате сополимер содержит до примерно 20 мол.% альфа-олефина, а в другом реакторе полимеризуют смесь пропилена и альфа-олефина CH2=CHR', где R' -- алкильный радикал, имеющий 2-10 атомов углерода, получая в результате сополимер, содержащий от 5 до 40 мас.% упомянутого олефина, в количестве 5-30% от общей массы полимера, причем систему полимер-катализатор, полученную в первом реакторе, подают в другие реакторы.A method of producing LLDPE with increased processability by gas-phase polymerization carried out in two or more reactors, in which (any order) in one of the reactors a mixture of ethylene and alpha-olefin CH 2 = CHR is polymerized, where R-alkyl having 1-10 carbon atoms, the resulting copolymer contains up to about 20 mol.% alpha-olefin, and in another reactor a mixture of propylene and alpha-olefin is polymerized CH 2 = CHR ', where R' is an alkyl radical having 2-10 carbon atoms, resulting in a copolymer containing from 5 to 40 wt.% mentioned olefin, in an amount of 5-30% of the total weight of the polymer, and the polymer-catalyst system obtained in the first reactor is fed to the other reactors.
