Abstract
By processing fibres and filaments of thermotropic polymers from anisotropic melt, films and mouldings having predeterminable properties are formed.
Claims10
A process for the production of films and mouldings from a sheet-like structure of thermotropic polymer fiber or filaments, comprising precompacting the sheet-like structure at a temperature below the melting point of the thermotropic polymer to substantially eliminate cavities between the fibers or filaments within the sheet-like structure, heating said sheet-like structure to obtain an anisotropic melt, followed by compacting and cooling of the sheet-like structure.
