Polyolefin
A polyolefin is any of a class of polymers produced from a simple olefin (also called an alkene with the general formula CH) as a monomer. For example, polyethylene is the polyolefin produced by polymerizing the olefin ethylene. Polypropylene is another common polyolefin which is made from the olefin propylene.
