Abstract: 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.

Abstract: A method of making a homogeneous mixture of polyolefin solids and liquid additive without melting the polyolefin solids during the making. The method comprises applying acoustic energy at a frequency of from 20 to 100 hertz to a heterogeneous mixture comprising the polyolefin solids and the liquid additive for a period of time sufficient to substantially intermix the polyolefin solids and the liquid additive together and while maintaining temperature of the heterogeneous mixture above the freezing point of the at least one liquid additive and below the melting temperature of the polyolefin solids, thereby making the homogeneous mixture without melting the polyolefin solids.
