| Abstract: | CONCLUSION. Research into degradation and ageing of polymers is extremely intensive and new materials are being synthesized with a pre-programmed lifetime. New stabilizers are becoming commercially available although their modes of action are sometimes not thoroughly elucidated. They target the many possible ways of polymer degradation: thermolysis, thermo-oxidation, photolysis, photooxidation, radiolysis etc. With the goal to increase lifetime of a particular polymeric material, two aspects of degradation are of particular importance: - Storage conditions, and - Addition of appropriate stabilizers. A profound knowledge of degradation mechanisms is needed to achieve the goal. |
