High Quality Content by WIKIPEDIA articles! A polyolefin is a polymer produced from a simple olefin (also called an alkene with the general formula CnH2n) as a monomer. For example, polyethylene is the polyolefin produced by polymerizing the olefin ethylene. An equivalent term is polyalkene this is a more modern term, although polyolefin is still used in the petrochemical industry. Polypropylene is another common polyolefin which is made from the olefin propylene. Polyolefin elastomer (or POE) is a relatively new class of polymers that emerged with recent advances in metallocene polymerisation catalyst. It represents one of the fastest growing synthetic polymer. POE?s can be substituted for a number of generic polymers including ethylene propylene rubbers (EPR or EPDM), ethylene vinyl acetate (EVA), styrene-block copolymers (SBCs), and poly vinyl chloride (PVC).
