Abstract
Color-stable rheology controlled polyolefin compositions and methods of making are described. A color-stable rheology controlled polyolefin composition can include a controlled rheology grade thermoplastic polyolefin, and an effective amount of a trisamide-based compound that imparts color-stability to the composition. The color-stable solid-state thermoplastic polyolefin composition can have a Hunter b value color change (Δb) rate of ≤0.03/day when stored at 93° C. for 50 days.
