A NEW FUNCTION FOR DIPOLE ORIENTATION AND RUBBER ELASTICITY.
Abstract
A new function for dipole orientation is derived to describe a collection of fixed, randomly oriented molecules with a dipole moment, achievable by an intramolecular motion such as inversion. This model should be applicable to tertiary amines in the glassy state or imbedded in a glassy matrix. The new function, called the Y function, is similar to the Langevin function at low fields. However at very high fields, the Y function predicts an average dipole moment rather than the value obtained from the Langevin function. The Y function has also been applied to obtain a new equation of state for rubber elasticity at high strains, in the same manner that had previously been achieved starting with the Langevin function (freely-rotating model). This new equation of state for rubber elasticity is superior to that based on the Langevin equation in that it predicts a finite rather than an infinite strain energy. (Author)
