| titleOfInvention | Diaryl carbinol metathesis catalysts |
| abstract | A catalyst and process for the metathesis polymerization of cyclic olefins, such as dicyclopentadiene, are disclosed. The catalyst comprises the reaction product of a transition metal halide preferably tungsten, molybdenum, or tantalum halides and a diaryl carbinol of formula (I) wherein G is independently C1-12 alkyl, C1-12 alkoxy, C1-12 alkylamino, C6-20 aryl, halide, or C1-6 haloalkyl; g is independently 0 to 4; R is independently hydrogen or G or the Rs are combined as a single bond or as a bridging group X, where X is CH2, CH2CH2, O, S, SO, SO2 or NR?1, and R1¿ is H or C¿1-6? alkyl. Optional co-catalysts include borohydrides, organo tin hydrides and organo aluminum compounds. Polymerization can be carried out in a reaction injection molding process to prepare a molded article. |
