摘要： 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.
The invention also relates to the use of a heat-generating organic dye adsorbing in the red to near-infrared, for reshaping a thermoplastic polymer article; bonding together two thermoplastic polymer or elastomer articles; separating two pieces of a thermoplastic polymer or elastomer article; self-healing or self-repairing a thermoplastic polymer article; recycling a composite polymer composition; recycling or depolymerizing a polymer; and/or separating two articles bonded by a polymer layer.-

摘要： The present invention relates to compositions (self-thermally) curable on demand under the triggering action of UV-visible to near-infrared irradiation of moderate intensity, method of using same for accelerated photopolyaddition of cyclic ether-amine resins or ultrafast dark curing of cyclic ether-amine resins, and articles obtained by such method. The invention also relates to a resin casting, film or coated substrate, and an adhesive layer or bonding agent, comprising a cyclic ether-amine resin obtained by an accelerated curing process according to the invention. The invention additionally relates to the use of a composition of the invention for increasing the delamination strength of laminated composite materials.
