Abstract
Official abstract text for this publication.
A family of novel hybrid compounds comprise a hindered phenolic scorch retardant and an allyl isocyanurate cure co-agent. Combining these two functionalities into a single molecule provides a synergy between the allyl isocyanurate and phenolic groups that achieves an improved balance between curing and scorch.
First claim
Opening claim text (preview).
The invention claimed is: 1. A composition comprising: (A) An ethylene-based polymer, (B) A peroxide, and (C) a hybrid scorch retardant/cure coagent selected from at least one compound of Formula IC-2, IC-3, or IC-4: wherein the composition comprises from 0.20 to 0.25 weight percent of the hybrid scorch retardant/cure coagent, the composition, when crosslinked, having a crosslinking density expressed as “MH-ML@180° C.” from 2.85 dN·m to 3.49 dN·m. 2. An article compromising the composition of claim 1 . 3. The article of claim 2 in the form of a wire or cable sheath. 4. A composition comprising: (A) An ethylene-based polymer, (B) A peroxide, and (C) a hybrid scorch retardant/cure coagent selected from at least one compound of Formula IC-2, IC-3, or IC-4: wherein the composition comprises from 0.60 to 0.70 weight percent of the hybrid scorch retardant/cure coagent, the composition, when crosslinked, having a crosslinking density expressed as “MH-ML@180° C.” from 2.51 dN·m to 3.76 dN·m.
