Abstract : The effect of ultraviolet light on the strength of stressed polymeric fibers and films was examined. Sixteen different polymeric materials exhibited identical characteristics with respect to the relationship of their durability when under stress and subjected to UV light. An empirical equation was found. This relationship is explained by the superimposition of two breakdown processes--a fluctuation process and the process of destruction due to the action of light. Specific physical terms can be attached to the parameters of the empirical equation. This empirical relationship can be used in determining light stability of stressed polymers. (Author)
