Abstract:
The effective implementations for materials of polymeric structure require fixing the shelf life for them. The broad usages of this kind of materials (e.g., medicaments, engineering goods, food packaging,..., etc.) Impose upon scientists well understanding of the effects produced by various work circumstances factors (heat, light and UV radiation, oxygen, ozone, chemical substances, water vapor). Over a long term of the affecting, these factors acquire an essential role in polymeric aging. Considering of the produced alteration in the polymeric physical and chemical properties shows subjecting of these features of mathematical models. The ultimate durability of the stabilized polymer can be speculated. Moreover, using the technique of aging acceleration for polymer gives great results in this field. This paper recall shortly a review of a number of methods of account the impacting factors on degradation of polymers. As well as, it presents some examples of the postulated lifetime of rubber. The methods of describing degradation of polymers are present as well, through using the artificial accelerated aging, and extrapolation way from the induced thermal deterioration: the Arrhenius model.
