This thesis is part of the subject photodegradation and biodegradation of polymer that can be or not from renewable resources. Its main objective is to study the photochemical durability of various polymers or polymer blends used particularly in agriculture and therefore subject to weathering. The chemical structure of polymers is one of the main parameters that could influence the photodegradation. A set of (co)polyesters containing units aliphatic, cyclic and / or aromatic have been selected in order to express the relationships structure / photodurability. The photoageing of materials was carried out under natural and accelerated conditions. Photo-oxidation mechanisms have been suggested for each material based on the evolution of the vi...
