Abstract
Carbon monoxide-containing polymers are disclosed which are heatable with high frequency (HF) electromagnetic radiation, including RF-frequencies and MW-frequencies, and which are used in imparting RF-sealability in structures, packaging material, laminates, and the like, including, e.g., multi-wall bags or containers, and co-extruded laminates.
