Abstract: The present disclosure provides a method for crosslinking polyolefins through using a substantially-miscible, polyolefin-based, silane-crosslinkiiig-agent carrier and related moisture- crosslinkable polyolefin-based compositions. The method is for crosslinking a first polyolefin includes the steps of: (A) selecting a second polyolefin being substantially-miscible with the first polyolefin and having particles of a morphology selected from the group consisting of powder and substantially spherical; (B) admixing the second polyolefin to the first polyolefin; (C) adsorbing a silane-crosslinking agent onto the second polyolefin, thereby rendering a substantially-miscible, polyolefin-based, silane-crosslinking-agent carrier; (D) melt blending the first polyolefin and the substantially-miscible, polyolefin-based, silane- crosslinking-agent carrier, thereby yielding a moisture-crosslinkable polyolefin-based composition; and (E) crosslinking the moisture-crosslinkable polyolefin-based composition.
