    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.

    Abstract: A method of forming a compatibilized polymeric blend may include providing a polyolefin that includes a propylene heterophasic copolymer. The polyolefin may have an ethylene content of at least 10 weight percent based on a total weight of the polyolefin. The method may include melt blending the polyolefin with a polylactic acid and a reactive modifier to form the compatiblized polymeric blend. The reactive modifier may be a glycidyl methacrylate grafted polypropylene (PP-g-GMA). The reactive modified may be produced by contacting a polypropylene, a glycidyl methacrylate, a multifunctional acrylate comonomer, and an initiator under conditions suitable for the formation of PP-g-GMA having a grafting yield in a range from 1 wt. % to 15 wt. %.

    Abstract translation: 形成相容的聚合物共混物的方法可以包括提供包含丙烯异相共聚物的聚烯烃。 基于聚烯烃的总重量，聚烯烃可以具有至少10重量％的乙烯含量。 该方法可以包括将聚烯烃与聚乳酸和反应性改性剂熔融共混以形成相容的聚合物共混物。 反应性改性剂可以是甲基丙烯酸缩水甘油酯接枝聚丙烯（PP-g-GMA）。 反应性改性可以通过在适于形成PP-g-GMA的条件下使聚丙烯，甲基丙烯酸缩水甘油酯，多官能丙烯酸酯共聚单体和引发剂接触而制备，所述PP-g-GMA的接枝收率在1wt。 ％至15wt。 ％。
