WebThe stress-strain behavior of a polymer greatly depends on the temperature. At very low … WebIn polymers, there are covalent bonds between the atoms of the polymer, but the polymeric macromolecules (or chains) are kept together by Van der Waals forces. Of all the four types of bonds, Van der Waals is the weakest. For this reason, polymers are very elastic (e.g., a rubber band), can be easily melted, and have low strength.
