Abstract: A vulcanizing agent is added during the processing of a polymer, and can form a crosslinking structure network in the polymer, thereby improving the mechanical properties of the material. Furthermore, the crosslinking agent can also de-crosslink the polymer material at a high temperature, and after being cooled, same can be crosslinked again to produce a network structure, thus endowing the polymer material with thermoplasticity for repeated processing.

Abstract: A propylene copolymer, a preparation method therefor, and an application thereof are provided. The copolymer forms a cross-linked network by means of a reaction between a furan-containing propylene copolymer and a small molecule of a coupling agent, thereby achieving a chemical bond connection between a polypropylene resin phase and an ethylene-propylene copolymer elastomer phase, fundamentally strengthening the force between the two phases, and improving the mechanical properties of a material. Meanwhile, the copolymer can achieve the decrosslinking of a material during melt processing such that the material has thermoplasticity, and after cooling, it can be crosslinked again to produce network structure.
