Telene Process BE Goodrich dicyclopentadiene polydicyclopentadiene (Telene ) [R3NH]2y 6.Mo,Oy/ Et2AlCl/ROH/SiCl4 ... 

RIM technology has been developed mainly by the BFGoodrich Co., under the trade name Telene, and by Hercules Inc., under the trade name Metton. The latter is now produced by Metton America, Inc. in Houston, USA, who have also licensed their process to the Teijin-Metton Co. in Japan. 

In the Telene process the procatalyst is a tetrakis(tridodecylammonium)-octamolybdate, activated with a mixture of Et2AlCl, propanol and SiCU. Up to 10% trimer of cyclopentadiene is added to the monomer to increase crosslinking in the polymer, while the trimer also lowers the melting point of DCPD. The of the product is typically 150 °C. BFGoodrich has licenced their process to the Japanese company Nip n Zeon Co., which produces it under the trade name Pentem. In the USA Helene RIM polymers are presently produced by APT, LLC, a joint venture of BFGoodrich and Advanced Polymer Technologies, LLC, recently renamed Cymetech, LLC. 

It should be noted that today there are industrial processes based on ROMP of norbornenes such as manufacturing of polynorbornene rubber (trade mark Nor-sorex ) and polycyclopentadiene thermoset material (trade marks Telene and Metton ). Both processes use effective classical Ru- and W- catalysts of the first generation [176].
