Make a schematic plot of the logarithm of relaxation modulus versus temperature for a lightly crosslinked polymer. Illustrate how the behavior is expected to change with increase in cross-linking density. (On the same graph, plot three curves to demonstrate lightly cross- linked, medium cross-linked, and highly cross-linked for a given material)

You must select a high stiffness polymer. How do you expect the tensile modulus of the following polymers compare: 1) Atactic PVC having an average molecular weight of 500,000 g/mol 2) Isotactic PVC having an average molecular weight of 500,000 g/mol a) 2 will have a greater tensile modulus than 1 b) 1 will have a greater tensile modulus than 2 c) They exhibit about the same tensile modulus

The Voight Model simulates the behavior of a viscoelastic polymer by placing a hookian and a viscous element in parallel. a)    Write an equation for the stress strain behavior of the Voight model b)    What are the conditions of stress and strain that define the creep and stress relaxation of the polymers? c)     In a creep experiment, how would you expect the stress of the polymer to change as a function of time if: h >> G G>>h

You are given a sample of polymer; it is not obvious if it is cross-linked, filled or not filled. Explain how you would determine the Tg (glass transition temperature).Regarding the polymer in question, if your manager asks you to use it for a product that would typically be used above Tg and in a humid environment. What technical concerns do you need to explain to your manager so that they fully understand any possible risks?
