Popis:	A kinetics of the orientation of a commercial liquid crystalline copolyester (60 mol% p-hydroxybenzoic acid/40 mol% ethylene terephthalate) in the magnetic field (6 T) was studied by means of X-ray measurements. The data were analyzed in terms of the domain model and the lattice model simulation. The rates of the magnetic orientation from an initial random state of orientation were found to be of 10−4 to 10−2 s−1 depending on temperatures. The comparison of the results obtained by the domain model and by the simulation suggested that the inter-domain interaction is important to explain the experimental result obtained for the reorientation process.
