METHOD FOR PLASTIC DEFORMATION OF POLYMERS BY ELECTROMAGNETIC RADIATION

摘要

The invention relates to a method for the plastic deformation of a polymer. The method is characterised in that the polymer is treated by electromagneti c radiation at a wavelength of 0.8 - 100 ~m and is also subjected to the effec ts of pressure and shearing in addition to thermal energy. The inventive method enables the plastic deformation of polymers, such as chitin and especially cellulose, which were hitherto unable to be subjected to plastic deformation .
