Abstract
A method of modifying the rheology of a thermoplastic resin that includes the steps of providing a thermoplastic resin and blending interpolymer resin particles with the thermoplastic resin. The interpolymer resin contains a styrenic polymer intercalated within a polyolefin, such that the thermoplastic resin is present as a continuous phase and the interpolymer resin is present as a dispersed phase. The method provides a rheology modified thermoplastic resin with improved physical characteristics.
