This invention discloses a highly elastic and resilient vinyl elastomer and its preparation method. The method includes: solution polymerization of ethylene, comonomers, and functional monomers in the presence of a catalyst to obtain a vinyl copolymer precursor; subsequently, dissolving the precursor in an organic solvent, adding a ring-closing reagent to perform an intramolecular ring-closing reaction, and adding a monofunctional end-capping agent to terminate the reaction; and obtaining the vinyl elastomer after separation, washing, and drying. By controlling the monomer feed in stages, a gradient structure is formed in the molecular chain, with ethylene-rich segments at both ends and α-olefin-rich segments in the middle. Combined with the intramolecular ring-closing structure, topological constraints are introduced, significantly improving the material's elastic recovery performance while maintaining thermoplastic processability. The resulting material exhibits a resilience of over 63%, a compression set of less than 24%, a melt strength of over 7.1 cN, and a gel content of less than 1.2%.

This utility model discloses a sponge with good resilience, comprising a sponge base layer, a rebound material layer, a sponge interlayer, a mesh layer, a sponge surface layer, and a protective layer. The sponge base layer, rebound material layer, sponge interlayer, sponge surface layer, and protective layer are bonded together in sequence from bottom to top, and a mesh layer is provided between the sponge interlayer and the sponge surface layer. The rebound material layer has a wavy structure, and the upper surface of the rebound material layer is adapted to the lower surface of the sponge interlayer. The wavy structure increases the contact area between the rebound material layer and adjacent sponge layers, which can better disperse and absorb external forces. The combination of crests and troughs allows the rebound material layer to better disperse and absorb pressure when subjected to external forces, avoiding excessive compression of the sponge, reducing sponge deformation and collapse, and ensuring its performance stability. When the external force acting on the sponge is removed, the sponge can quickly return to its original shape, significantly improving the sponge's resilience.
