Outline of lecture

Polymers are macromolecules that can give rise to a wide range of complex behaviors, depending on how these molecules are arranged at microscopic length scales (i.e., the microstructure). Beyond the more standard liquid and crystalline states of matter, polymers can also appear in more unusual phases, such as the glassy phase, the rubber or elastomeric phase. This richness in behavior, as well as the fact that numerous tools have been developed over the last 50 years to synthesize and commercialize these materials makes them extremely useful in application. They have replaced more traditional materials, such a metals and wood, in a huge number of applications, and this trend will apparently continue. In this course an overview of the physical properties of polymers will be presented with the objective of making contact with the mechanical properties of such materials in the solid state.

Purpose of lecture

Mechanics of solid polymers.
