Abstract: A method of forming articles from acrylonitrile-butadiene-styrene, the method comprising: feeding a monomer stream comprising a petrochemical monomer into a reactor; contacting the petrochemical monomer with a polymerization activator within the reactor to produce a polymerized stream comprising rubber, latex, or a combination thereof and withdrawing the polymerized stream from the reactor; passing the polymerized stream through a filter to produce a filtered product stream, wherein the filter is a continuously self-cleaning filter; passing the filtered product stream through a grafting unit comprising acrylonitrile and styrene to produce acrylonitrile-butadiene-styrene; and forming an article from the acrylonitrile-butadiene-styrene, wherein the article is an extruded sheet, a molded part, or a combination thereof.
