Polymer Technology

• Compute number- and mass average molar masses from given distributions (Poisson, Flory, …)
• Describe the statistics of polymer configurations.
• Describe the connection between chemical structure and crystallinity
• Use the Flory-Huggins model for the thermodynamics of polymer solutions
• Describe critical conditions for formation of networks (percolation, Bethe lattice)
• Predict the shear modulus for polymer networks from the crosslink density and functionality
• Explain experimental methods for determination of thermal properties (glass transition …)
• Model the mechanical behavior of polymer networks in large strain
• Use viscoelastic models to compute the complex moduli (G’ and G”)
• Compute the viscosity of polymer melts as function of molar mass and temperature
