Abstract

The ring opening metathesis polymerisation of 7,8-(bistrifluoromethyl)tricyclo[4.2.2.0 2.5]deca-3,7,9-triene using Schrock-type molybdenum alkylidene initiators yields precursor polyacetylene with well defined chain-ends, molecular weights and polydispersities. The precursor polyenes can be thermally converted to the equivalent polyene structures by elimination of hexafluoroxylene. Truly monodisperse soluble oligoene sequences were separated and isolated using reversed-phase HPLC techniques.
