“…while the net effect of such actions is reflected in changes of polymer thermal properties. The recombination and reduction of free radicals when an irradiated polymer is heated at relatively low temperatures has been reported by various authors (Burillo et al, 2002b;Jahan et al, 2001). Fig.…”

“…Plastics packaging materials represent a large percentage of municipal solid waste due to their ever increasing applications and to their high volume/weight ratio (Burillo et al, 2002b;Arvanitoyiannis and Bosnea, 2001). Given that these materials have a relatively short life span as food containers, an important approach is their reuse after recycling.…”

“…It is of particular interest to study the effect of irradiation on multilayer packaging materials containing a buried layer of recycled polymer (i.e. LDPE) in terms of thermal, mechanical and permeation properties given that in specific applications irradiation is used for the improvement of polymer properties through irradiation-induced crosslinking (Burillo et al, 2002b).…”

“…Indeed, such highly energetic irradiations yield bond cleavages and free radicals allowing chemical rearrangements or oxidation in the presence of air, crosslinking and further chain scission reactions in the g-irradiated material. These modifications are closely linked with the g-irradiation conditions such as the dose rate, the integral dose delivered, the nature of the atmosphere or the temperature [14,13,8,31,38].…”

Polymeric materials are exposed to high energy radiation either deliberately to alter their properties or inadvertently during their use in high dose environments. As a consequence, an understanding of how radiation modifies the polymer structure, and hence properties, is essential for many applications. In addition, the understanding of the degradation of polymers with light or heat can benefit from knowledge of the reaction pathways of radical and charged species formed on irradiation with high energy photons. This article aims to provide a broad overview of the fundamental processes occurring during radiolysis of polymers. This is achieved through a discussion of the interaction of high energy photons with matter, and the subsequent reactions of mainly radical intermediates. Polymers either cross‐link or degrade on exposure to radiation, and the final properties of the polymers depend critically on the balance of these two main reaction pathways. A number of examples are taken from the literature to illustrate how the tendency to undergo cross‐linking or main‐chain scission depends on the polymer structure. The overall yield of reactions can be greatly reduced by the introduction of aromatic groups into the polymer structure. On the other hand, yields can be increased by the inclusion of radiation‐sensitive groups such as sulfones. Similarly, the rates of reactions and the balance between cross‐linking and scission can depend sensitively on the radiolysis temperature. While this review focuses on a discussion of the reactions occurring on radiolysis in vacuo, the effect of the presence of dissolved oxygen on the reaction pathways is also discussed.
