✦ Synopsis
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.

ANtract--Mechanical properties are presented for LDPE samples naturally weathered for various periods both in the absence and the presence of a light stabilizer system. Qualitative property/structure correlations are proposed, taking into account also previous structural results for the same samples

## Abstract Thermo‐oxidative degradation of low density polyetylene (LDPE) at a low degree of volatilization (about 4%) at 264–289°C was studied. Gas chromatography—mass spectrometric analysis was used to separate and identify the products of LDPE decomposition. Altogether 44 compounds representing
