Oligo HOMOs

The mechanism of electron-impact elimination of the substituents of oligo(organyl-silsesquioxanes) and their homo derivatives is discussed in °- >. [Pg.231]

Oligo(organylsilsesquioxanes) and their homo derivatives can be used for the preparation of ladder polymers displaying a very high heat resistance and thermo-oxidative resistance... [Pg.234]

Somewhat greater success has been reported in respect of homo-oligo-merization of olefins, though once again reports are few, and focused predominantly on nickel. The complexes TpxNiCl (Tpx = TpMs 13, TpMs 14, TpMs 15 Ms = mesityl, Tpw = HB(pzN4s)2(pz5Ms), TpMs = HB(pzMs) (pz5 ) were screened in the presence of methylaluminoxane (MAO) cocatalyst at 0 °C under 30 bar ethylene. Under these conditions, both 13 and 14 showed appreciable activity, with very high selectivity for 1-butene (95-96%) within the C4 fraction, equivalent to 81% selectivity overall.13 In contrast, 15 was found to be completely inactive under these conditions. [Pg.194]
