The shape memory of polymers is a property that allows an object deformed by means of a physical stress to recover its initial shape under the effect of another stress. Most commonly, the initial stress is mechanical and is applied at a temperature above room temperature, while the return to the initial shape is achieved by heating.

When characterizing a polymer, several pieces of information must be determined

Polymeric materials are composed of monomer units of extremely diverse chemical nature and size. Moreover, they can take several forms, linear, branched, or cross-linked. Each of these characteristics will induce different properties on the final material. In order to ensure the conformity of polymers to customer specifications, their characterization is necessary.

Beyond the chemical nature, a polymer has a specific characteristic: an important molar mass. It is defined thanks to the following terms :
