Modeled structures of natural or modified regenerated natural polymers, and method for manufacturing (Machine-translation by Google Translate, not legally binding)

摘要

Modeled structures, especially fibers, filaments or films, which consist of, or contain, natural or regenerated polymers, such as proteins, cellulose, or their derivatives, v.gr, cellulose acetate, which are characterized by the fact that an acidic compound, preferably an unsaturated organic acid, or a functional derivative thereof, has been grafted onto the polymer subjected thereto in its solid form and patterned to ionizing radiation, such as bombardment by radiation with high energy particles and/or ionizing electromagnetic radiation and contacting the polymer with the unsaturated organic acidic compound before, during or after irradiation.
