## Abstract A multilayered sample with alternatively superposed poly(butylene terephthalate) (PBT) and nonpolar polymer/clay sheets was elaborately prepared to investigate the whole hybridization process of polar polymer. The kinetics of PBT melt intercalation was studied by a rheological approach.
The structural development during the melt spinning and subsequent annealing of polybutene-1 fibers was studied with in situ wide-angle X-ray scattering techniques. The online spinning apparatus consisted of a vertically translating extruder that allowed different distances from the spinneret to the
