On Shrinkage and Molecular Extension.
Abstract
When an oriented polymer is heated, it often retracts towards an isotropic state. The change in shape is a measure of the extension of the molecules in the oriented sample. The several different functions that have been used to define molecular extension are derived and reviewed. It is concluded that the ratio (oriented length/shrunk length) is the most appropriate, and that a direct test by neutron scattering would be feasible. Originator-supplied keywords include: network extension, shrinkage, and retraction.
