What are Polyolefin Polymers? Polyolefins are macromolecules formed by the polymerization of olefin monomer units. The IUPAC nomenclature term for polyolefins is poly(alkene). The most common polyolefins are polypropylene (PP) and polyethylene (PE). These polymers are prevalent in a wide…READ MORE >
