Abstract:
A method for processing an impact modifier material having a core and shell molecular structure, the method comprising working the impact modifier material in a mild extruder to a state such that at least a portion of the shells of the impact modifier material fuse together to form an impact modifier material output; and pelletizing the impact modifier output, said impact modifier material comprises methacrylate butadiene styrene, acrylonitrile butadiene styrene, acrylonitrile styrene acrylic, or any combination comprising at least one of the foregoing impact modifier materials, said method further comprising maintaining a processing temperature at a softening temperature, wherein the shells of the core and shell structures fuse and the core of the core and shell structures are minimally disrupted when worked by the mild extruder at the softening temperature.
