    Abstract: Crosslinkable polymeric compositions for use in, for instance, cable insulation layers, are disclosed. The crosslinkable polymeric compositions comprise an ethylene-based polymer, an organic peroxide, a crosslinking coagent, and a methyl-radical scavenger comprising at least one derivative of 2, 2, 6, 6-tetramethyl-1-piperidinyloxy (“TEMPO”), such as 4-acryloxy-2, 2, 6, 6-tetramethylpiperidine-N-oxyl, 4-allyloxy-2, 2, 6, 6-tetramethylpiperidine-N-oxyl, and bis (2, 2, 6, 6-tetramethyl-1-piperidinyloxy-4-yl) sebacate, and combinations of two or more thereof, wherein ratio of crosslinking coagent to organic peroxide is less than 1.72:1 on a molar basis. A crosslinked article prepared from a crosslinkable polymeric composition is also disclosed, the crosslinkable polymeric composition comprising, inter alia, a methyl-radical scavenger comprising at least one TEMPO derivative. In addition, a coated conductor comprising a conductive core and a polymeric layer at least partially surrounding the conductive core is disclosed, wherein at least a portion of the polymeric layer comprises the crosslinked article.

    Abstract: Provided is a sprayable polyurethane coating, comprising the reaction product of an isocyanate component and an isocyanate-reactive component, wherein the isocyanate component includes an isocyanate, and the isocyanate-reactive component includes a cardanol-modified epoxy polyol. The cardanol-modified epoxy polyol is a reaction product of an epoxy component and an epoxy-reactive component at a ratio of epoxy groups to epoxy reactive groups from 1:0.95 to 1:5, and the epoxy-reactive component includes a cardanol component. A sprayable polyurethane based reaction system comprising the sprayable polyurethane coating and a process for forming the sprayable polyurethane coating are also provided.
