Yamazaki reviewed well the industrialization and application development of cycloolefin polymers (27).

In this study, rheological behavior of cycloolefin (COC)/G and EG composites were investigated in detail.

Rheological behavior of cycloolefin copolymer/graphite composites

Replication of sub-micron features using amorphous thermoplastics

Besides Exxon's and Dow's work in catalyst development, significant metallocene catalyst technology has been developed by Chisso, Exxon, and Hoechst for isotactic polypropylene (iPP); by Hoechst and Mitsui Petrochemical for cycloolefin copolymers; by Fina and Mitsui Toatsu for syndiotactic polypropylene (sPP); and by Dow and Idemitsu for syndiotactic polystyrene.

Dow and Idemitsu are sampling syndiotactic polystyrene to customers for specialty molding applications, and Mitsui Petrochemical and Hoechst are selling cycloolefin polymers into engineering thermoplastic applications, such as compact discs.
