Ring opening metathesis polymerization catalyst incorporation

The ring-opening metathesis polymerization of norbomene monomers functionalized with arene complexes of cyclopentadienyliron has been reported using Grubbs catalyst. These polymerization reactions proceeded rapidly to produce the corresponding polynorbomenes (32 and 33). It was found that the incorporation of bulkier aromatic groups in the sidechains of these materials increased their glass transition temperatures and thermal stability.
