This course serves as an introduction to concepts in polymer chemistry, polymer science and polymer engineering. This includes a discussion of the mechanisms of step growth, chain growth and ring-opening polymerizations with a focus on industrially relevant polymers and processes. The description of polymers in solution as well as the solid state will be explored. Several modern polymer characterization techniques are introduced including gel permeation chromatography, differential scanning calorimetry, thermal gravimetric analysis and others.
