Abstract
Procedure for the production of a polyethylene with improved resistance to stress cracking and impact, characterized in that a small amount of an additive selected from those with the following general formula is added to the polymer: **(See formula)** where R is a hydrocarbon chain that may be constituted by an alkyl, alkenyl or cycloalkyl radical; (R2O) n is a polyether chain in which R2 is an alkyl radical, as such or substituted by alkyl, arylene, cycloalkylene, aralkylene groups, and n is a number between 1 and 100; R1 can be a radical selected from those listed for R and, in this case, R and R1 form a single hydrocarbon group with a number of carbon atoms that varies between 5 and 30, or it can be an aryl radical, in which if the sum of the carbon atoms of R and R1 again varies between 5 and 30, R1 can also be selected from those listed for R2 and, in this case, the polyether chain increases by one unit; X is a group selected from (see formula), where Me is any monovalent metal and R0 is a hydrocarbon radical selected from those previously listed.
