Polynorbornene is obtained via ring opening polymerization of Norbornene. The polymer has a molecular weight of round 3000000 g/mol and is roughly 30 times higher than standard grades of NBR. The distribution of cis and trans groups in the polymer prevent crystallization. The polymer is amorphous with glass transition of around 37° C.
The polymer has a high affinity to hydrocarbons and can absorb around 10 times of its own weight of oil. Also 300 phr of various fillers can be added, giving a reasonable rubber compound.
