    摘要: Provided is a composite material which is in pellet form and which has particles with a core-shell structure, where the core of the particles has one or more magnetic materials, and the shell is made of silicon dioxide, and the pellet has one or more crosslinkable polyethylene and/or polyethylene-containing copolymers. Also provided is a process for crosslinking polyethylenes, by mixing the composite material, one or more free radical initiators, and at least one polyethylene, and heating the mixture inductively.

    摘要: Composite material which is in pellet form and which comprises particles with a core-shell structure, where the core of the particles comprises one or more magnetic materials, and the shell comprises silicon dioxide, and which comprises a polyethylene crosslinkable in the presence of a heat-activatable free-radical initiator and/or polyethylene-containing copolymers. Process for the crosslinking of polyethylenes, by mixing the composite material, one or more heat-activatable free-radical initiator(s) and at least one polyethylene, and heating the mixture inductively.
