  • USE OF RED TO NEAR-INFRARED HEAT-GENERATING ORGANIC DYES FOR REPROCESSING/RECYCLING POLYMERS
    Publication number: 20230374253
    Abstract: The present invention relates to a process for bringing a polymer composition above a threshold temperature on demand, wherein: the polymer composition comprises 0,01 to 0,5% weight of at least one heat-generating organic dye that generates heat above the threshold temperature when exposed to a given range of red to near-infrared irradiation, and the process comprises exposing the polymer composition to red to near-infrared irradiation at a wavelength within the red to near-infrared range where the heat-generating organic dye generates heat above the threshold temperature, the weight % being expressed with respect to the total weight of the polymer composition. The threshold temperature may be the glass transition temperature, the depolymerization temperature, the melting temperature, or the decomposition temperature of the polymer composition.
