Document Type and Number:
WIPO Patent Application WO/2023/240938
Kind Code:
A1
Abstract:
Provided in the present application are a reversibly crosslinked polyethylene cable material and a preparation method therefor. The raw materials of the reversibly crosslinked polyethylene cable material in the present application comprise a polyethylene copolymer and a coupling agent, wherein the polyethylene copolymer is obtained by copolymerizing polymerization monomers, the polymerization monomers comprising ethylene, and vinyl-benzaldehyde and/or a vinyl-benzaldehyde derivative, and the coupling agent is selected from polybasic primary amine compounds. The reversibly crosslinked polyethylene cable material of the present invention has the advantages of excellent heat resistance and wide process window.
