In this review

state-of-the-art technology of polyolefin-based elastomer manufacture

including major producers and product trademarks

grades and properties were summarized. Research and developments on production process and catalyst system for the ethylene-propylene binary and ternary rubbers(EPM

EPDM

mEPDM)

the poly(ethylene-

co-α

-olefin) elastomer(POE)and the poly(ethylene-

block-α

-olefin) elastomer(OBC)were also introduced. It has been pointed out that the thermoplastic elastomer

such as POE and OBC

and the polyolefin plastomer not only had excellent mechanical and physical properties of polyolefin-based elastomer

but also was easy molding and pro

cessing

and can be recycled and reused. And the metallocene catalyst had the advantages of high activity

good ability to catalyze copolymerization with

α

-olefin

and single active site. In order to independently develop the polyolefin-based elastomer

the thermoplastic elastomer and plastomer with more excellent performance and more profitable

such as mEPDM

POE and OBC et al

the researches on the metallocene catalyst with high temperature adaptability and the high temperature solution polymerization process must be strengthened.
