NOVELTY - An ultraviolet curing solvent-free pressure-sensitive adhesive comprises 90-100 parts mass isooctyl acrylate, 15-20 parts mass acrylic acid, 2-4 parts mass hydroxyethyl acrylate, 3-5 parts mass N,N-dimethylacrylamide, 7-9 parts mass heat stabilizer, 1-3 parts mass photoinitiator and 2-4 parts mass chain transfer agent. USE - Ultraviolet curing solvent-free pressure-sensitive adhesive. ADVANTAGE - The ultraviolet curing solvent-free pressure-sensitive adhesive improves thermal stability of pressure-sensitive adhesive. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of ultraviolet curing solvent-free pressure-sensitive adhesive, which involves (S1) mixing isooctyl acrylate, acrylic acid, hydroxyethyl acrylate and N,N-dimethylacrylamide, stirring until the mixture is uniformly mixing, adding chain transfer agent and photoinitiator, and continuously stirring until the mixture is completely dissolving to obtain mixture, and (S2) introducing nitrogen into mixture, after the mixture is filled with the nitrogen, turning on ultraviolet lamp, after the mixture is irradiated for 20 seconds, turning off ultraviolet lamp, and continuously stirring until reaction is completed, and cooling to room temperature.
