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: 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): (R1CO2)2 A1OH (I), (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. 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: 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): (R1CO2)2 A1OH (I), (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.

L'invention concerne un procédé de production d'un polymère à base d'oléfine, ledit procédé comprenant la polymérisation d'au moins un monomère, en phase gazeuse, ou dans un procédé en suspension, en présence d'au moins l'un des composants suivants : A) au moins un catalyseur, B) au moins un cocatalyseur, C) une composition comprenant au moins un composé choisi parmi les composés de formule (I) et/ou au moins un composés choisi parmi les composés de formule (II) : (R1CO2)2 A1OH (I), (R2)xN(R3OH)y (II); dans lesquelles R1 représente un radical hydrocarboné contenant 13 à 25 atomes de carbone, R2 représente un radical hydrocarboné contenant 14 à 26 atomes de carbone, R3 représente un radical hydrocarboné contenant 1 à 4 atomes de carbone, et x + y = 3, et x vaut 1 ou 2. L'invention concerne également un procédé de production d'un polymère à base d'oléfine, ledit procédé comprenant la polymérisation d'au moins un monomère en présence d'au moins l'un des composants suivants : A) un catalyseur de type Ziegler Natta comprenant au moins deux métaux de transition, B) un composé trialkylaluminium, C) en option, une composition comprenant au moins un composé choisi parmi les composés de formule (I) et/ou au moins un composés choisi parmi les composés de formule (II) : (R1CO2)2 A1OH (I), (R2)xN(R3OH)y (II); dans lesquelles R1 représente un radical hydrocarboné contenant 13 à 25 atomes de carbone, R2 représente un radical hydrocarboné contenant 14 à 26 atomes de carbone, R3 représente un radical hydrocarboné contenant 1 à 4 atomes de carbone, et x + y = 3, et x vaut 1 ou 2.
