Zusammenfassung:Provided are high temperature, low scorch, including no scorch, which is defined herein, methods of making crosslinkable compound compositions, the method comprising melt compounding a primary stream at a temperature of from 120.0° to 150.0° C., wherein the primary stream comprises one or more thermoplastic polyolefins and one or more antioxidants, but lacks curative additives selected from the group consisting of: peroxides and crosslinking coagents; and injecting into the compounded melt a combination of curative additives comprising one or more organic peroxides and one or more crosslinking coagents, and homogeneously mixing the one or more thermoplastic polyolefins, one or more antioxidants, one or more organic peroxides, and one or more crosslinking coagents by melt compounding them together. Also provided are methods of making crosslinked compound compositions and manufactured articles.
