Abstract: | The effects of natural weathering on mechanical properties and chemical structure of low density polyethylene have been studied. It is found that no simple correlation exists between the development of carbonyl groups and mechanical properties such as stress or strain at break or elastic modulus. It appears that there is recovery in the mechanical properties during the winter months. |
