A process for producing an olefin-based polymer, said process comprising polymerizing at least one monomer, in the gas phase, or in a slurry process, in the presence of at least the following components:n A) at least one catalyst; B) at least one cocatalyst; C) a composition comprising at least one compound selected from formula (I), and/or at least one compound selected from formula (II): nn (R1CO 2 ) 2 AlOH (I), n (R2) x N(R3OH) y (II); wherein R1 is a hydrocarbon radical containing from 13 to 25 carbons; R2 is a hydrocarbon radical containing from 14 to 26 carbons; R3 is a hydrocarbon radical containing from 1 to 4 carbons; and x+y=3, and x has a value of 1 or 2. n A process for producing an olefin-based polymer, said process comprising polymerizing at least one monomer in the presence of at least the following components:n A) a Ziegler Natta type catalyst comprising at least two transition metals; B) a trialkylaluminum compound; C) optionally a composition comprising at least one compound selected from formula (I), and/or at least one compound selected from formula (II): nn (R1CO 2 ) 2 AlOH (I), n (R2) x N(R3OH) y (II); wherein R1 is a hydrocarbon radical containing from 13 to 25 carbons; R2 is a hydrocarbon radical containing from 14 to 26 carbons; R3 is a hydrocarbon radical containing from 1 to 4 carbons; and x+y=3, and x has a value of 1 or 2. |
