Grubbs’ catalysts polynorbornenes

Recently, Sannino and co-workers studied the activity of Grubbs catalyst- functionalized MWCNTs by the ROMP synthesis of polynorbornene. The activities of the and 2 generation Grubbs catalysts loaded on to CNTs were found to be similar in the ROMP of 2-norbornene. The eharacterization of polynorbornene-CNT composites confirmed the good dispersibility of the nanotubes in the polymer matrix. ... [Pg.157]

Ring-opening metathesis polymerization has also been exploited to build blocks from cyclic olefins, especially polynorbornene [5]. The development of ROMP for block copolymer synthesis has recently been facilitated by the introduction of functional-group-tolerant metathesis catalysts by Grubbs [21]. [Pg.5]
