Abstract
Disclosed is a process for adding stabilizers and, optionally, additives to polyolefins in particle form obtained in liquid monomer by means of Ziegler-Natta catalysts, where the addition of stabilizers and, optionally, additives is carried out in liquid monomer in a step that follows polymerization, but precedes the flashing of the liquid monomer, after the aluminum alkyl has been deactivated.
