Abstract

One of the major problems with any sealant system is its susceptibility to hostile environments, such as heat, moisture, ultraviolet radiation, oxygen, mechanical stress and biochemical attack. Prolonged exposure to these environments leads to substantial changes in physical, chemical, mechanical and rheological properties over time. Since sealants are polymeric in nature, any chemical modification is directly related to the corresponding mechanical-rheological changes. The present chapter demonstrates the importance of investigating both chemical and mechanical-rheological properties of sealants upon exposure to harsh environments. The usefulness of chemorheological tools is exemplified by the use of a model system based upon styrene-butadiene-styrene triblock copolymer.
