  • Patent number: 11382330
    Abstract: An organic/oil mixture used in an emulsion to form micro-capsules of the present disclosure. The organic/oil mixture includes abamectin; a non-polar solvent having a polarity (P) value of a Hansen solubility parameter of 0 to 3; a polar solvent of Formula (I): where R1 is a C1 to C15 alkyl; R2 is either H or a C1 to C8 alkyl; R3 is a C1 to C15 alkylene; and R4 is a C1 to C15 alkyl, where a sum of carbons in the R1, R2, R4 alkyls and R3 alkylene is 8 to 30; and 2.5 to 20 wt. % of an isocyanate, where each wt. % is based on the total weight of the organic/oil mixture and the sum of the wt. % of the abamectin, the non-polar solvent, the polar solvent and the isocyanate totals 100 wt. %.

  • Patent number: 10851221
    Abstract: Crosslinkable polymeric compositions for use in, for instance, cable insulation layers, 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-piperidinyloxyl (“TEMPO”), 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 conducttor 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.
