Abstract
A process for preparing a profile of thermotropic polymer having a large cross-section, with improved tensile strength and tensile elasticity moduli, comprising first forming a bundle of fibers or filaments of at least one thermotropic polymer and continuously heating the thus formed bundle to a temperature sufficient to form an anisotropic melt and then passing the anisotropic melt through a shape-giving unit.
