According to the invention, a method for the plastic deformation of a polymer is provided, which is characterized in that the polymer is treated with electromagnetic radiation having a wavelength in the range from 0.8 to 100 µm with simultaneous action of pressure and shearing and thermal energy. By means of the method according to the invention, it is also possible to plastically deform polymers which have to date not been accessible to plastic deformation, such as chitin and in particular cellulose.
L'invention concerne un procédé de déformation plastique d'un polymère, qui se caractérise en ce que le polymère est traité par action simultanée de pression et de cisaillement, ainsi que d'énergie thermique, avec un rayonnement électromagnétique, dans une longueur d'ondes de l'ordre de 0,8 à 100 µm. Le procédé selon l'invention permet même la déformation plastique de polymères qu'il n'était jusqu'alors pas possible de soumettre à déformation plastique, comme la chitine et en particulier la cellulose.
