Abstract

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.
