Abstract
An interesting phenomenon is reported on the formation of rodlike textures of poly(butylene terephthalate) (PBT). When an amorphous film and a film having spherulitic textures were annealed under pressure, rodlike textures arranged randomly were formed. They were observed by means of polarizing microscopy and light scattering measurement. Moreover, for an elongation of the film for which no superstructure was observed by polarizing microscopy, the rodlike textures were oriented at a particular angle with respect to the stretching direction and formed networks.
