Our recent finding of magnetic orientation of diamagnetic crystalline polymers was interpreted in view of the liquid crystallinity of these polymers. It is well known that the magnetic orientation of liquid crystalline polymers is due to the existence of the anisotropic domain which can rotate under the magnetic torque. On the other hand, the process of polymer crystallization is regarded as a transition from an isotropic phase (glass or melt) to an anisotropic phase (crystal). It would therefore be intuitively acceptable to consider that an intermediate phase should occur in the transition where polymer chains should assume a partially anisotropic state that might resemble the liquid crystalline state. In analogy to the liquid crystalline polymers, if a magnetic field is applied during the transition, the orientation could occur. In this report, this scheme is examined for poly(ethylene-2,6-naphthalate) and isotactic polystyrene.
