In this paper, we will report the industrial production method and properties of polyolefin elastomers (POEs) and their applications. Most POEs are random copolymers of ethylene-co-1-butene (EB) and ethylene-co-1-octene (EO). These POEs are generally produced by solution polymerization in a hydrocarbon solvent with unique catalyst systems that enable efficient co-monomer incorporation and ability to attain lower crystallinity than traditional polyolefin products. Their physical properties are greatly dependent on co-monomer type, co-monomer content and molecular weight. POEs are used in a variety of applications, including impact modifiers for automotive polypropylene (PP) based compounds. This paper will further describe new POEs including olefin block copolymers (OBCs) and super high flow POEs.
