ABSTRACT
The macromolecules that constitute low-density polyethylene (LDPE) are made chiefly of sequences of the monomer, but they contain groups different from aliphatic groups, of great importance for the polymer’s stability with respect to the action of outdoor agents. The most important groups are the following:
Tertiary carbon atoms due to branching reactions during polymerization.
Ketone groups formed through slow oxidation reactions during storage or in the course of hot-working processes to obtain manufactured goods, granules, or films.
Vinyl and vinylidene groups formed during synthesis or product manufacturing processes.
