  • Patent number: 9416264
    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. %.
