    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. %.

  • Patent number: 9388310
    Abstract: A composition that contains from 30 to 95 wt. %, based on the total weight of the composition, of a thermoplastic component and an effective amount of a flow-enhancing component. The effective amount of the flow-enhancing component reduces the viscosity of the composition by at least 10% compared to the viscosity of a composition comprising the thermoplastic component, but not an effective amount of the flow-enhancing component. The thermoplastic component is selected from the group consisting of polycarbonates, polyesters, and combinations thereof. The flow-enhancing component comprises b1) a component selected from the group consisting of metal oxides, metalloid oxides, metal alkoxides, metalloid alkoxides, and combinations thereof and b2) a mineral filler component. The weight ratio of component b1) to component b2) ranges from 1:25 to 25:1. A method for enhancing the flow of compositions comprising thermoplastic components is also disclosed.

  • Patent number: 9175157
    Abstract: The present invention provides a polypropylene resin composition in a mixture of a pellet (A) and a pellet (B), which is characterized by mixing them with various inorganic fillers and additives, wherein the pellet (A) comprises a long fiber-reinforced composite resin (a) obtained via a pultrusion impregnation process, and the pellet (B) comprises a composite resin (b) that includes polypropylene and thermoplastic elastomer. The polypropylene resin composition of the present invention can directly replace thermoplastic elastomer overmolding or painting in automotive parts to which such processes are routinely applied (e.g., interior components of the vehicle), which makes it possible to simplify and reduce the cost of the production process for such parts.
