Abstract

A method for processing polyolefins may include contacting solid polyolefins with a solid catalyst to form a reaction mixture. The solid catalyst may be chosen from a zeolite, a microporous aluminosilicate, an alumina, or combinations thereof. The solid polyolefins may be chosen from polyethylene, polypropylene, or combinations thereof. The method may include mechanically agitating the reaction mixture to produce olefin-containing hydrocarbon polymers and separating the olefin-containing hydrocarbon polymers from the solid catalyst. The olefin-containing hydrocarbon polymers include a carbon-carbon double bond in the backbone of the hydrocarbon polymers.
