    Abstract: A styrene monomer reclamation process and system is described. The styrene monomer reclamation process includes providing a waste plastic. The waste plastic includes styrenic polymers. The waste plastic is formed into polymer particles. At least a portion of the polymer particles are dissolved in a solvent to form a polymer stream. The dissolved polymer particles are depolymerized to form a styrene monomer stream.

    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.
